Development Ross Bagdasarian Jr., the son of Alvin and the Chipmunks creator Ross Bagdasarian Sr. who revived the franchise after his father's death, dreamed of making a live-action Alvin film since 1997, "and the dream has had many nightmare moments." On September 17, 2004, Fox 2000 Pictures, 20th Century Fox Animation and Bagdasarian Productions announced they would collaborate to create a live-action computer-generated film starring Alvin and the Chipmunks. On April 17, 2005, Jon Vitti was revealed to be writing the screenplay. On January 24, 2007, it was announced Tim Hill was in talks with Fox to direct the film. Casting Chevy Chase, Jim Carrey, Tim Allen, John Travolta, Ben Stiller, Vince Vaughn, and Bill Murray were originally considered for the role of David Seville. On March 7, 2007, Jason Lee joined the project to play David Seville, and Cameron Richardson signed on March 21.

He was such an Alvin and the Chipmunks fan that he even owned the album Chipmunk Punk (1980), and studied 1980s Alvin cartoons for his role in the film. Filming Principal photography began on March 28, 2007, making it the first film to be produced under the leadership of Fox Animation president Vanessa Morrison. Seville's house was built on Sunset Gower Studios and contains references to Bagdasarian Sr.'s life. The set pieces included an upright piano he used to write his songs and a flower visual he painted; the house's address number includes 1958, the year he created the chipmunk characters; and the house design is based on a cottage built in 1919, the year Bagdasarian Sr. was born. In shots where Lee interacted with the chipmunks, the actor rehearsed with small stuffed animals indicating where the
