We've already told you about Moviefone's excellent Unscripted video with director Tim Burton and his Sweeney Todd star Johnny Depp, but now Cinematical has an exclusive clip from their chat that was left on the cutting room floor. Ever wondered why Depp and Burton take on so many films together? How do they operate on set? Are they close enough to communicate with only their eyes? Interestingly enough, it appears the two men speak to each other in Vulcan -- which, of course, makes it that much easier to give and receive notes at a fast pace. Hmmm ... Vulcan? After watching the clip above, be sure to check out the full Unscripted interview over at Moviefone. It's extremely rare to watch Burton and Depp interview one another (using your questions, of which I believe we received roughly 1000 or more), so definitely take a few minutes and dive in. Use the video as a primer before heading out to see Sweeney Todd: The Demon Barber of Fleet Street when it hits theaters this weekend. Enjoy.
