Johnny Depp Does Not Watch His Own Movies?

During an interview with David Letterman, Johnny Depp reveals that he does not watch any of his movies that he stars in.  Depp talks about himself as if its not him on screen.  Maybe there is another presence that takes over him once the camera's roll.  Either way, this seems quite sketch.

"I don't like watching myself.  I prefer the experience of making the film is great, the process is all fine....but then HE's up there."
