Down With Love (2003)

Factual error: When Renee Zellwegger arrives in New York, she exits her cab in front of the United Nations. The Canadian flag is visible. The movie is set in 1962, and the form of Canadian Flag in the shot was not adopted until 1965.

Continuity mistake: At the start of the movie, when Barbara crosses the road from Grand Central Station to catch the taxi, there is a blue car parked in front of it. Then when the shot is shown from the rear of the taxi, the blue car is gone. When the shot moves back to the side view, the blue car is back there again. In addition when the shot is taken from the side of the taxi, there is no green fence visible, however, when the shot is from the rear of the taxi, there is a shoulder-high green tubular fence on the footpath. (00:03:40)

Factual error: David Hyde Pierce mentions the Cuban Missile Crisis, which took place in October 1962. The time of year in the movie isn't entirely clear, but given the weather conditions it's almost certainly spring or summer, or several months before the Cuban Missile Crisis.

Trivia: The ending song scene, during the credits - singing wasn't strange to either of the actors: Zellwegger had a leading role in Chicago, and McGregor in Moulin Rouge, movies where they had several song scenes. In fact, the scene was only added at the insistence of the actors.

Trivia: The MAD Magazine Catcher Block reads with a parody of 1960s feminist Barbara Novak on the front was created specifically for the movie. A special 1960's-style cover was drawn by one of the MAD artists.

Trivia: Near the beginning of the film, Catcher Block makes the remark that Barbara Novak didn't sound like a blonde over the phone. As it turns out in the end, Barbara was not a natural blonde at all.

Theodore Banner: You're my creative team, create a reason to get rid of her or I'll create a new creative team.

Peter MacMannus: Catch, you are the best friend a guy with twenty diagnosed neuroses ever had.
Catcher Block: Oh, we've been friends a long time... I knew you when you only had twelve.

Vickie Hiller: At one point, I had even convinced myself that life was all one big zany sex comedy and you had switched keys with the lead to use his swinging pad to snare me.
Peter MacMannus: I did! I did switch keys with the lead.

Question: When the start credits are playing, is it Renee Zellweger and Ewan McGregor singing?
