On the DVD audio commentary for "Love Actually," Hugh Grant continuously mocks the looks and acting abilities of Firth (his sometimes on-screen rival), eventually encouraging his fellow-commentors writer/director Richard Curtis, and co-stars Bill Nighy and Thomas Sangster to join in on the mocking. Firth appears to have taken these comments in good nature and said that he and Grant seem to have a "Bette Davis-Joan Crawford" kind of relationship.

richard curtis, despite his success, must be one of the most easily overlooked and under-appreciated talents in movies. what he did with a looming disaster of a script (enough stories for 7 movies) is pure magic. and note how he managed the commentary track, assembling a small, wonderful group of folks in a room, seemingly letting them ramble, but guiding the session with his fine sense of what was coming in the movie. he brings the conversation around at appropriate times, almost unnoticeably. the handling of foul language and "sex" scenes in front of the young thomas sangster is exactly how it should be done. we can stop treating kids like morons, while still allowing that differences should be recognized and nuanced.
