Marmalade sandwich, anyone? Colin Firth told the Daily Mail on Thursday that he will be voicing Paddington Bear in a new live-action movie. The most British of bears is already the star of a beloved series of picture books, in which he is known for his politeness and habit of keeping a stash of his favorite sandwich under his hat. In his turn on the silver screen, Paddington will be computer-animated with the help of motion-capture devices on Firth's face. Also set to star in the film are Hugh Bonneville and Sally Hawkins as Mr. and Mrs. Brown, Paddington's adoptive family, and Nicole Kidman as an unspecified villain.
