Continuity mistake: When Uma Thurman visits the radio station for the first time, she asks Janeane Garofalo if she can sit down by the microphone. As she's standing in front of the desk she's wearing a cardigan with a handbag over her shoulder. When she turns round to say "you promise not to laugh?", the cardigan and bag have disappeared.
Continuity mistake: In the scene when Noelle goes to Brian's apartment so she will be there during Abby's radio show, at one point, Noelle is sitting on the coach with Brian in a chair next to her. Brian has just given her a book and they are leaning close, about to kiss. Noelle has dropped her hand away from her mouth, but the very next shot shows Brian moving her fingers away from her mouth to lean in and kiss her.
