Burton admits confusion working with green screen

Tim Burton was confused working with the green screen on 'Alice in Wonderland'.

The director admits the project was not made in the usual way he would like, and, as a result, found the process difficult.

He said: "It's completely opposite from the way I usually make a film. Usually the first thing I know is the vibe and feel of a scene. It's the first thing you see. Now it's the last thing you see. It's like actually being in 'Alice in Wonderland'. It's completely f***ed up."

The 51-year-old filmmaker - who was nominated for an Oscar for his directorial work on animated movie 'Corpse Bride' - told Interview magazine the process of shooting without seeing the results until after production left him "unsettled".

He said: "You understand that when you're shooting that some percentage of what you're filming isn't going to be exactly like what it ends up being, because so many elements are added later.

"It's in your head, and it can be unsettling. I did find it quite difficult because you don't see a shot until the very end of the process. Even when we were making 'Nightmare' or 'Corpse Bride', you'd get a couple of shots and know what the vibe was. This is completely a*s-backward."

Earlier this week Mia Wasikowska, who plays Alice in the adaptation of the Lewis Carroll novel, claimed she also had difficulties working with green screen technology.

She said: "When you're acting with a tennis ball that is supposed to be the Cheshire Cat, you don't know what the Cheshire Cat is giving you, so you're having to pretend you know."
