To get a look at Hollywood's finest up-and-coming and established actors and actresses, all one needs to do is look at the "Avatar" cast. The blockbuster science fiction flick, which was released in December of 2009, is centered around a handicapped marine, who, while on a mission, finds himself lost between two entirely different worlds (Pandora and Earth). "Avatar" takes place in the distant future.

  1. Sam Worthington stars as Jack Sully, who is the film's paraplegic main character. The young and charismatic Australian actor has an extensive history on television shows in his homeland, and broke out onto the Hollywood scene in the late 2000s with diverse roles in films such as "Terminator Salvation," "Clash of the Titans" and "Call of Duty: Black Ops."

  2. Zoe Saldana is an attractive and spirited young Dominican Republic-bred actress who has been a fixture on the Hollywood landscape since the beginning of the 2000s. One of Zoe Saldana's breakout roles was in the 2002 Britney Spears coming-of-age dramatic comedy, "Crossroads." Some of the actress' biggest film roles to date include movies such as "Star Trek," "The Losers," "Death at a Funeral" and "Pirates of the Caribbean."

  3. Sigourney Weaver is a veteran actress who in the film portrays Grace Augustine, a doctor who organizes the Avatar Program. The tall, New York City-born actress has received several Oscar nods and has acted in many notable films over the decades, including the "Alien" series, "The Village," "Gorillas in the Mist," "Working Girl," "Ghost Busters," "The Ice Storm" and "Dave."

  4. Giovanni Ribisi stars as Parker Selfridge, who heads up the Resources Development Administration (RDA) colony. The Los Angeles native has been acting since the early 1980s, and has an extensive array of films under his belt such as "Gone in Sixty Seconds," "Cold Mountain," "Lost in Translation," "Saving Private Ryan" and "Boiler Room."

  5. Michelle Rodriguez portrays a military pilot named Trudy in "Avatar." The Texas-born and New Jersey-bred actress, who has a tough girl reputation in Hollywood, first caught the public eye's attention with her turn in the 2000 female boxing film "Girlfight." Some of Michelle Rodriguez's other noteworthy movies are "S.W.A.T.," "Resident Evil" and "The Fast and the Furious."
