My take is that acting is acting. A performance is a performance. With performance capture, if you don't get the performance on the day, you can't enhance the performance.

Acting is a sort of pressure cooker that allows the fizz to come out the top. God knows what I'd be like if I didn't have that.

As long as you have the acting chops and the desire to get inside a character, you can play anything.

Animators do amazing working translating and interpolating the characters [in the Planet of the apes], the facial performances. What we're creating on set - if you don't get it on the day, in the moment, on set, in front of the camera, with the director and the actors. The emotional content of the scene and the acting choices.

But the first time I had to stand up and sing with them was when we did the pre-record for the movie and it was that moment where I sort of said to myself: "S**t, now I actually have to do this and I have to stand up and do my stars in your eyes moment!" Wake Up and Make Love With Me was the first song and I thought: "Here we are with Chaz and all the boys..."

On lower budget things you're still working collaboratively, but the investment and your level of creative importance is higher on something like this.

I just directed The Jungle Book with Cate Blanchet and Christian Bale.
