Captain America is a fictional superhero appearing in American comic books published by Marvel Comics. Created by cartoonists Joe Simon and Jack Kirby, the character first appeared in Captain America Comics #1 (cover dated March 1941) from Timely Comics, a predecessor of Marvel Comics. Captain America was designed as a patriotic supersoldier who often fought the Axis powers of World War II and was Timely Comics' most popular character during the wartime period. The popularity of superheroes waned following the war and the Captain America comic book was discontinued in 1950, with a short-lived revival in 1953. Since Marvel Comics revived the character in 1964, Captain America has remained in publication.
Captain America wears a costume that bears an American flag motif, and is armed with a nearly indestructible shield that he throws at foes. The character is usually depicted as the alter ego of Steve Rogers, a frail young man enhanced to the peak of human perfection by an experimental serum to aid the United States government's imminent efforts in World War II. Near the end of the war, he was trapped in ice and survived insuspended animation until he was revived in the present day. Although Captain America often struggles to maintain his ideals as a man out of his time with its modern realities, he remains a highly respected figure in his community which includes becoming the long-time leader of the Avengers.
​Captain America was the first Marvel Comics character to have appeared in media outside comics with the release of the 1944 movie serial, Captain America. Since then, the character has been featured in other films and television series, more recently in the Marvel Cinematic Universe (MCU) portrayed by Chris Evans in Captain America: The First Avenger, The Avengers, Captain America: The Winter Soldier, Avengers: Age of Ultron, Captain America: Civil War, and the upcoming Avengers: Infinity War (2018/2019).

Iron Man (Tony Stark) is a fictional superhero appearing in American comic books published by Marvel Comics, as well as its associated media. The character was created by writer and editor Stan Lee, developed by scripter Larry Lieber, and designed by artists Don Heck and Jack Kirby. He made his first appearance in Tales of Suspense #39 (cover dated March 1963).
An American billionaire playboy, business magnate, and ingenious engineer, Tony Stark suffers a severe chest injury during a kidnapping in which his captors attempt to force him to build a weapon of mass destruction. He instead creates a powered suit of armor to save his life and escape captivity. Later, Stark augments his suit with weapons and other technological devices he designed through his company, Stark Industries. He uses the suit and successive versions to protect the world as Iron Man, while at first concealing his true identity. Initially, Iron Man was a vehicle for Stan Lee to explore Cold War themes, particularly the role of American technology and business in the fight against communism. Subsequent re-imaginings of Iron Man have transitioned from Cold War themes to contemporary concerns, such as corporate crime and terrorism.
​Throughout most of the character's publication history, Iron Man has been a founding member of the superhero team the Avengers and has been featured in several incarnations of his own various comic book series. Iron Man has been adapted for several animated TV shows and films. The character is portrayed by Robert Downey Jr. in the live action film Iron Man (2008), which was a critical and box office success. Downey, who received much acclaim for his performance, reprised the role in a cameo in The Incredible Hulk (2008), two Iron Man sequels Iron Man 2 (2010) and Iron Man 3 (2013), The Avengers (2012) and Avengers: Age of Ultron (2015), Captain America: Civil War (2016), and will do so again in Spider-Man: Homecoming (2017) and both parts of Avengers: Infinity War (2018/2019) in the Marvel Cinematic Universe.

Bilbo Baggins is the title character and protagonist of J. R. R. Tolkien's 1937 novel The Hobbit, as well as a supporting character in The Lord of the Rings. In Tolkien's narrative conceit, in which all the writings of Middle-earth are translations from the fictitious volume of The Red Book of Westmarch, Bilbo is the author of The Hobbit and translator of various "works from the elvish" (as mentioned in the end of The Return of the King).

Frodo Baggins is a fictional character in J. R. R. Tolkien's legendarium, and primary character of The Lord of the Rings. Frodo is a hobbit of the Shire who inherits the One Ring from Bilbo Baggins and undertakes the quest to destroy it in the fires of Mount Doom. He is also mentioned in Tolkien's posthumously published works, The Silmarillion and Unfinished Tales.

Vin Diesel was born Mark Sinclair in Alameda County, California, along with his fraternal twin brother, Paul Vincent. He was raised by his astrologer/psychologist mother, Delora Sherleen (Sinclair), and adoptive father, Irving H. Vincent, an acting instructor and theater manager, in an artist's housing project in New York City's Greenwich Village. He never knew his biological father. His mother is white (with English, German, Scottish, and Irish ancestry), and his adoptive father is African-American.
His first break in acting happened by chance, when at the age of seven he and his friends broke into a theatre to vandalize it. A woman stopped them and offered them each a script and $20, on the condition that they would attend everyday after school. From there, Vin's fledgling career progressed from the New York repertory company run by his father, to the Off-Off-Broadway circuit. At age seventeen and already sporting a well-honed physique, he became a bouncer at some of New York's hippest clubs to earn himself some extra cash. It was at this time that he changed his name to Vin Diesel.
Following high school, Vin enrolled as an English major at Hunter College, but dropped out after three years to go to Hollywood to further his acting career. Being an experienced theatre actor did not make any impression in Hollywood and after a year of struggling to make his mark, he returned to New York. His mother then gave him a book called "Feature Films at used Car Prices" by Rick Schmidt. The book showed him that he could take control of his career and make his own movies. He wrote a short film based on his own experiences as an actor, called Multi-Facial (1995), which was shot in less than three days at a cost of $3,000. Multi-Facial (1995) was eventually accepted for the 1995 Cannes Film Festival where it got a tumultuous reception.

Afterwards, Vin returned to Los Angeles and raised almost $50,000 through telemarketing to fund the making of his first feature, Strays (1997). Six months after shooting, the film was accepted for the 1997 Sundance Film Festival, and although it received a good reception, it did not sell as well as hoped. Yet again Vin returned disappointed to New York only to receive a dream phone call. Steven Spielberg was impressed by Multi-Facial (1995) and wanted to meet Vin, leading him to be cast in Saving Private Ryan (1998). Multi-Facial (1995) earned Vin more work, when the director of The Iron Giant (1999) saw it and decided to cast Vin in the title role. From there, Vin's career has steadily grown, with him securing his first lead role as Richard B. Riddick in the sci-fi film Pitch Black (2000). The role has earned him a legion of devoted fans and the public recognition he deserves.
Since then, he has headlined a series of blockbusters, often but not only centered on fast-driving motor vehicles: The Fast and the Furious (2001), xXx (2002), The Pacifier(2005), Fast & Furious (2009), Fast Five (2011), Fast & Furious 6 (2013), and Furious Seven (2015). He also voiced Groot in Guardians of the Galaxy (2014) and starred in the lower-budgeted courtroom drama Find Me Guilty (2006), the latter directed by Sidney Lumet.

Dwayne Douglas Johnson was born in Hayward, California on May 2nd 1972 to Ata Johnson (née Maivia) and Canadian-born professional wrestler Rocky Johnson. His father is of Black Nova Scotian descent, and his mother is of Samoan background (her own father was Peter Fanene Maivia, also a professional wrestler). While growing up, Dwayne traveled around a lot with his parents and watched his father perform in the ring. During his high school years, Dwayne began playing football and he soon received a full scholarship from the University of Miami where he had tremendous success as a football player. In 1995, Dwayne suffered a back injury which cost him a place in the NFL. He then signed a 3 year deal with the Canadian League but left after a year to pursue a career in wrestling. He made his wrestling debut in the USWA under the name Flex Kavanah where he won the tag team championship with Brett Sawyer.
In 1996, Dwayne joined the WWE and became Rocky Maivia where he joined a group known as "The Nation of Domination" and turned heel. Rocky eventually took over leadership of the "Nation" and began taking the persona of The Rock. After the "Nation" split, The Rock joined another elite group of wrestlers known as the "Corporation" and began a memorable feud with Steve Austin. Soon the Rock was kicked out of the "Corporation". He turned face and became known as "The Peoples Champion". In 2000, the Rock took time off from WWE to film his appearance in The Mummy Returns (2001). He returned in 2001 during the WCW/ECW invasion where he joined a team of WWE wrestlers at The Scorpion King (2002), a prequel to The Mummy Returns (2001).
He has since appeared in several films, including The Rundown, The Game Plan, Get Smart, The Other Guys and Faster. As an actor, he is perhaps best known for his portrayals of Luke Hobbs in The Fast and the Furious franchise.
