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.
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.
Three of the most popular forms of coffee making are shown in this movie. When Kassie is unpacking her things, a drip coffee carafe is being unboxed. Next, at a restaurant when Kassie meets Roland for the first time, there is a French press at their table. Finally, the pour-over method is shown at Leonard's house. A Chemex glass coffee maker is shown in the background.
