Paul Giamatti on Golden Globe-winning Barney's Version

Actor Paul Giamatti has won a Golden Globe for his portrayal of Barney Panofsky, a grumpy but amusing self-destructive man with big appetites.

Giamatti spoke to Talking Movies' Tom Brook about why he is drawn to playing men with unflattering characteristics - people who, in his own words, are unpleasant and strange.
