In 2005, Jimmy appeared in the film Hostage, where he starred with Bruce Willis, and The Amityville Horror, where he played the role of the middle child of a family moving into a haunted house. The films were released in March and April, respectively. He was called "Jimmy Two-Takes" on the set of "Hostage", because of his ability to deliver his lines perfectly.
In February 2006, Jimmy appeared in the thriller Firewall, where he played the son of Harrison Ford's character. He also played an abused boy in The Heart Is Deceitful Above All Things, an independent film that was released a month after Firewall.

His 2007 roles include South of Pico, an independent film, and Evan Almighty, a sequel to the 2003 film Bruce Almighty. He is due to appear as a young James T. Kirk in the upcoming Star Trek movie.
