Animated movie adventure Monsters Inc has beaten Harry Potter and Lord of the Rings to win best film at the British Academy Children's Film and Television Awards.

Monster's Inc, which features the voices of John Goodman and Billy Crystal as main characters Sulley and Mike, won an Oscar this year for best song.

Meanwhile ITV1's Saturday morning show SM:tv walked off with best entertainment show at the ceremony held at the Hilton Hotel in London.

This is the third year the show has won the award, despite the loss of popular presenters Cat Deeley, Ant McPartlin and Declan Donnelly to other high-profile projects.

SM:tv, now presented by Tess Daly and Big Brother 2 winner Brian Dowling, also won the Lego/Bafta Kids Vote award which was chosen by viewers.
