When Francisco X. DeJesús found out his company would be in charge of the computer animation for Tim Burton’s “Alice in Wonderland,” he didn’t react the way most people would. Knowing that a visionary filmmaker like Burton was entrusting them to help create an entire new cinematic world for him, DeJesús, digital effect supervisor for Sony Imageworks, was actually a bit disappointed.

“When it first came up, my first thought was ‘Darn!’ because I was already working on another project,” DeJesús told EXTRA during a phone interview explaining that his work on the guinea pig adventure “G-Force” prevented him from starting the project. “Knowing that [Burton] was going to be here working with Imageworks and that I wasn’t going to be working with him was kind of a bummer.”

Once on vacation after “G-Force” was completed, DeJesús received a welcomed phone call.

“It turned out the scope of work on ‘Alice in Wonderland’ had grown and they needed more people,” DeJesús said. “They wondered if I would be interested and I said, ‘Yeah!’”

DeJesús, who has worked on such films as “Titanic” and the “Spider-Man” franchise, was brought into “Alice in Wonderland” specifically for the final battle sequence where Alice and the White Queen’s army face off against the Jabberwocky and the Red Queen’s army.

During our interview, DeJesús, who was born in Puerto Rico, talked about how the vision behind “Alice in Wonderland” was different from any other movie he’s ever worked on in the past and what types of challenges he faced coming onto the film late in the game.

“Alice in Wonderland” will be available on DVD and Blu-ray June 1.
