Johnny Depp has revealed the secret behind the success of his and director Tim Burton's working relationship - they speak their own language.

The pair are currently working on their fifth movie together, Corpse Bride, and both admit they share a secret bond that makes their partnership both successful and fun.

Depp says, "There's a lot of shorthand that a lot of people don't understand when we are on the set, that makes perfect sense to me and to him."
