Race To Witch Mountain - Cast

Cast

• Dwayne Johnson as Jack Bruno who is a Las Vegas cab driver, a former convict. The director wrote in a cab driver as a main character because there was a unique relationship between the driver and his passengers. Fickman explained, "When Dwayne's driving and two aliens appear in his cab, he's stuck with them, there is an implied contract that I will get you to your destination, because that's what he does." This is Dwayne Johnson's second Disney film, the first one being the 2007 family comedy film The Game Plan, also directed by Andy Fickman.
• AnnaSophia Robb as Sara, sister of Seth, a girl with telekinetic and telepathic powers. Fickman chose Robb based on her performance in Bridge to Terabithia. She is very kind to Bruno and is the more compassionate of the two siblings. The only time she does not refer to Jack by his full name (Jack Bruno) is when she says goodbye to him, when she refers to him only as "Jack".
• Alexander Ludwig as Seth, brother of Sara, a boy with the power to control his molecular density - "phasing" and becoming very dense to some degree of invulnerability. He is very cold to Bruno at first, not trusting him very much, but apologizes in the end saying that if it were not for him they would have not finished their mission. Both siblings talk using overly formal, emotionless voices, and are always addressing Bruno by both his first and last name in all situations.
• Ciarán Hinds as Henry Burke, Leader of Project Moon Dust. He is very sarcastic and unscrupulous, having no regard to morality as demonstrated after Seth and Sara are imprisoned in Witch Mountain when he orders them to be experimented on so he can harness their powers, regardless of the possibility that they could die. To him, as long as he gets results, whether they live or die does not matter to him. Hinds described his character as a man in black, explaining, "I'm the head of the operation who's contacted directly by a man you never see... is about protecting the country. He's responsible for it, and he'll do whatever needs to be done. That's how he sees it."
• Carla Gugino as Dr. Alex Friedman, a discredited astrophysicist. Fired from her university, she is relegated to giving a lecture at a UFO conference about hard science. She is named for Stanton T. Friedman, the Nuclear Physicist and noted Ufologist. She also becomes Jack's love interest. Fickman cast Gugino into the role since he was a fan of the short-lived television series Threshold, in which the actress starred.
• Tom Woodruff, Jr. as The Siphon, A well-trained alien assassin.
• Garry Marshall as 'Harlan' a friend of Alex's and an author of books who thinks he can "tell when people are lying to me". He is seen tricking Burke into going after him by trading cars with Jack.
• Cheech Marin as Eddie Cortez, the auto mechanic who gets frustrated when people come to his shop in the middle of the night, when it is closed.
• Chris Marquette as Pope.
• William J. Birnes, the host of UFO Hunters, in a cameo.
• Whitley Strieber, author of Communion, in a cameo.

Kim Richards and Ike Eisenmann, who portrayed Tia and Tony in the original Witch Mountain films of the 1970s, made cameo appearances in Race to Witch Mountain. Richards appears as a roadhouse waitress (named "Tina," a minor change from the character she played in the 1975 and 1978 films) and Eisenmann appears as Sheriff Anthony. In addition, Meredith Salenger, the star of Disney's 1985 adventure The Journey of Natty Gann has a cameo as a TV reporter named "Natalie Gann."
