Cast of Spiderman
• Tobey Maguire as Peter Parker / Spider-Man: Born in 1984, Peter is an academically brilliant but socially inept student who is bitten by a genetically modified spider and gains spider-like abilities. Maguire was cast as Peter in July 2000, having been Sam Raimi's primary choice for the role after he saw The Cider House Rules. The studio was initially hesitant to cast someone who did not seem to fit the ranks of "adrenaline-pumping, tail-kicking titans", but Maguire managed to impress studio executives with his audition. The actor was signed for a deal in the range of $3 to $4 million with higher salary options for two sequels.To prepare, Maguire was trained by a physical trainer, a yoga instructor, a martial arts expert, and a climbing expert, taking several months to improve his physique.[Maguire studied spiders and worked with a wire man to simulate the arachnidlike motion, and had a special diet.
The studio had expressed interest in actors Leonardo DiCaprio, Freddie Prinze, Jr, Chris Klein, Wes Bentley, and Heath Ledger.DiCaprio had been considered by James Cameron for the role in 1995, while Raimi joked of Prinze that "[he] won't even be allowed to buy a ticket to see this film." In addition, actors Scott Speedman, Jay Rodan, and James Franco were involved in screen tests for the lead role.
• Willem Dafoe as Norman Osborn / Green Goblin: CEO of Oscorp who tests an unstable strength enhancer on himself and becomes the insane and powerful Green Goblin. Unaware of Spider-Man's true identity, he also sees himself as a father figure for Peter, ignoring his own son, Harry. Dafoe was cast as Osborn in November 2000. Nicolas Cage, John Malkovich, and Jim Carrey turned down the role. Dafoe insisted on wearing the uncomfortable costume as he felt that a stuntman would not convey the character's necessary body language. The 580-piece suit took half an hour to put on.
• Kirsten Dunst as Mary Jane Watson: The girl whom Peter Parker has developed a crush since he was six years old. Mary Jane has an abusive father, and aspires to become an actress, but becomes a waitress at a run down diner, a fact she hides from her boyfriend Harry. Before Raimi cast Dunst, he had expressed his interest in casting Alicia Witt. Dunst decided to audition after learning Maguire had been cast, feeling the film would have a more independent feel.Dunst earned the role a month before shooting in an audition in Berlin.
• James Franco as Harry Osborn: Before being cast as Peter's best friend and flatmate, Franco had screen tested for Spider-Man himself.
• Cliff Robertson as Ben Parker: The husband to May Parker and uncle of Peter Parker, a fired electrician who is trying to find a new job. He is killed by a carjacker whom Peter failed to stop, and leaves Peter with the message, "With great power comes great responsibility."
• Rosemary Harris as May Parker: The wife to Ben Parker and the aunt of Peter Parker. May is a devout Christian who is highly aware of Peter's love for Mary Jane.
• J. K. Simmons as J. Jonah Jameson: The grouchy publisher of the Daily Bugle who considers Spider-Man a criminal. Nonetheless he has a good side and pays Peter for photos of Spider-Man, and refuses to tell the Green Goblin the identity of the photographer.
• Joe Manganiello as Flash Thompson: A repugnant high school student who bullies Peter, and is defeated in a fight after Peter inherits his spider powers.
• Michael Papajohn as The Carjacker: The criminal who robs the wrestling manager who stiffs Peter Parker for his ring performance and murders Ben Parker (although the murderer was retconned as Flint Marko / Sandman in Spider-Man 3). He was killed from falling from a window when confronted by Peter. In Spider-Man 3, it is learned that his name is Dennis Carradine.
• Bill Nunn as Joseph "Robbie" Robertson: The kindly editor at the Daily Bugle, who on occasion helps Peter.
• Elizabeth Banks as Betty Brant: As seen in past Spider-Man comics, Betty Brant is Jameson's secretary who has a bit of a soft spot for Peter.Bruce Campbell, a long-time colleague of director Sam Raimi, cameoed as the announcer at the wrestling ring Peter takes part in. Raimi himself appeared off-screen, throwing popcorn at Peter as he enters the arena to wrestle Bonesaw McGraw (played by former professional wrestler "Macho Man" Randy Savage). Spider-Man co-creator Stan Lee also had a cameo, in which he asks Peter, "Hey kid, would you like a pair of these glasses? They're the kind they wore in X-Men." The scene was cut, and Lee only briefly appears in the film to grab a young girl from falling debris during the battle between Spider-Man and the Green Goblin in Times Square. R&B/soul singer Macy Gray appears as herself. Lucy Lawless also appears as a punk rock girl. One of the stunt performers in this film is actor Johnny Tri Nguyen. Kickboxer Benny "The Jet" Urquidez has an uncredited cameo as a mugger.
