the Marshall College location, and a picture on Jones's desk, saying he died shortly after Indiana's father. Shia LaBeouf as Mutt Williams, a young, motorcycle-riding greaser and Indiana's sidekick and son. The concept of Indiana Jones having offspring was introduced in The Young Indiana Jones Chronicles, in which Old Indy is shown to have a daughter. During development of Kingdom of the Crystal Skull, this idea was incorporated into Frank Darabont's script, with Indiana and Marion having a 13-year-old daughter. However, Spielberg found this too similar to The Lost World: Jurassic Park, so a son was created instead. Koepp credited the character's creation to Jeff Nathanson and Lucas. Koepp wanted to make Mutt into a nerd, but Lucas refused, explaining he had to resemble Marlon Brando in The Wild One; "he needs to be what Indiana Jones's father thought of [him]—the curse returns in the form of his own son—he's everything a father can't stand". LaBeouf was Spielberg's first choice for the role, having been impressed by his performance in Holes. Excited at the prospect of being in an Indiana Jones film, LaBeouf signed on without reading the script and did not know what character he would play. He worked out and gained of muscle for the role, and also repeatedly watched the other films to get into character. LaBeouf also watched Blackboard Jungle, Rebel Without a Cause and The Wild One to get into his character's mindset, copying mannerisms and words from characters in those films, such as the use of a switchblade as a weapon. Lucas also consulted on the greaser look, joking that LaBeouf was "sent to the American Graffiti school of greaserland". LaBeouf pulled his rotator cuff when filming his duel with Spalko, which was his first injury in his career, an injury which worsened throughout filming. He later pulled his groin. Additionally, Igor Jijikine portrays Russian Colonel Antonin Dovchenko, Spalko's second-in-command. His character stands in for the heavily built henchmen that Pat Roach played in the three previous films, as Roach died in 2004 from throat cancer. Joel Stoffer and Neil Flynn have minor roles as FBI agents Taylor and Paul Smith interrogating Indiana in a scene following the opening sequence. Alan Dale plays General Ross, who protests Indiana's innocence. Andrew Divoff and Pasha D. Lychnikoff play Soviet agents Grant and Roosevelt, respectively. Spielberg cast Russian-speaking actors so their accents would be authentic. Ilia Volok
