Diane Sawyer was apparently perfectly happy for her image to be used in Jason Bateman's masturbation scene.
After arguing with Kassie, Wally is seen walking in the rain. A truck passes behind him bearing an ad featuring a turkey baster. This is a reference to 'The Baster', the short story on which the film was based.
Aniston revealed in the DVD 'extras' that she had known Bateman since she was 25, and the producers and directors noted their good chemistry in working together.
Reputedly Jennifer Aniston wasn't terribly happy about the change in the film's title from the fairly distinctive "Baster" to the more generic The Switch (2010).
The film differs drastically from Jeffrey Eugenides' story "Baster" which features an unattractive man in love with a beautiful woman. The writer had nothing to do with the film, as he felt it was going "too Hollywood".
