Factual error: When Julia Roberts and her roommate are in their living room and "I Love Lucy" comes on the TV, the opening theme song is accompanied by the traditional heart with "I Love Lucy" written on it. However, this movie takes place in 1953-1954, and that opening for the show wasn't used until the show was put in syndication many years later. During the show's primary run, cartoon characters of Lucy and Ricky opened the show.
Trivia: In one scene Julia Roberts takes her students to see a painting by Jackson Pollack. Julia's co-star Marcia Gay Harden won her Academy Award playing Pollack's wife in the movie, "Pollack" opposite Ed Harris, who incidentally played Julia's boyfriend/fiance in "Stepmom".
