Burton, Depp on Mad Hatter, "Sweeney Todd" Hysterics

ET interviewed Tim Burton and Johnny Depp and talked Alice in Wonderland. You can see the video interview here.

With Alice in Wonderland, Burton and Depp have made seven films together -- yet Depp hasn't seen a single one of them. The actor said his kids are more likely to see Alice before him. Burton says of Depp, "From working with him for so many years, the one thing I knew from the very beginning is that he goes for anything, and that's very exciting. ... That's what creation is all about."

Burton jokes of choosing Depp for the Mad Hatter character, saying, "After he lobbied for Alice, we went to the next logical character."

Depp explains why he continues to work with Burton, saying, "The atmosphere that he creates for that set is so conducive to creating essentially whatever you want and not being afraid to try something. ... There is the element of trust that's there."

Along with discussing Wonderland, Depp recalled how their previous collaboration, Sweeney Todd: The Demon Barber of Fleet Street, would put the director into fits of laughter. "It was the most normal I've ever looked in any of his films and that alone made me feel really uncomfortable," Depp tells ET's Mary Hart. "Then I'd come to the set and [Burton] would burst into hysterical laughter."
