Jack Black's sweet cartoons

Jack Black says working on an animated movie is "the sweetest job" ever.The actor - who has starred in films including 'The Holiday' and 'Nacho Libre' - admits voicing the lead character in new animated movie 'Kung Fu Panda' was easy compared to previous acting jobs.He said: "It's about the sweetest job you could have. You go in once a month, work for three or four hours, no hair, make-up and no costumes. You just roll out of bed, show up at noon, do some voice and they have it all scripted. "They encourage you to improvise so there's something to think about, but you just have to have fun in front of the microphone - you get all the fun of acting without all the pain in the a** of waiting for the cameras to focus."Jack - who has a 23-month-old son Samuel with his wife Tanya - also revealed his martial arts skills came in handy during the making of the movie.He added: "I used to do karate and judo when I was a child. I did them for a year, you know, the obligatory, 'Start something and then give up'? But, obviously I was great, and I knew all about the martial arts for this film."I actually did some of the moves for the movie - they get the camera on you so they can get the movements. But now I've seen it I feel angry - like the panda stole my soul!"
