Input: Question: Who was in charge of BBC One when A Matter of Loaf and Death was broadcast on the channel? Passage:Nick Park and the Aardman team also produce commercials and music videos, notably the video for Peter Gabriel's "Sledgehammer", which uses many different animation techniques, including pixilation involving Gabriel holding poses while each frame was shot and moving between exposures, effectively becoming a human puppet. More recently Aardman used this technique on a series of short films for BBC Three entitled Angry Kid, which starred a live actor wearing a mask. The actor's pose and the mask's expression had to be altered slightly for each exposure. Aardman has also created many films, of which some have become household names. Nick Park joined Aardman after they took interest in his college project, A Grand Day Out. Since then, Nick Park has directed the following films for Aardman: The Wrong Trousers, Creature Comforts, A Close Shave, "Cracking Contraptions", the feature film Chicken Run, and more recently, another feature film , co-produced with DreamWorks Animation. Nick Park's latest work is the new Wallace and Gromit short (30 minutes) called A Matter of Loaf and Death, broadcast on BBC One on Christmas Day 2008. Nick Park has won several Academy Awards for Best Animation.
