The Hangover

No effects or prosthetics were created for Stu's missing tooth. Ed Helms never had an adult incisor grow, and his fake incisor was taken out for the parts of filming where Stu's tooth is missing.

The formal name for "roofies" is given as "Ruphylin". The drug is really a trademark brand named Rohypnol, but was changed for the movie because the makers did not want to be associated with the depicted criminal activities.

First part of the end credits feature a collage of photos showing what happened that night.

In the UK, on the advice of the BBFC, the photographs of an elderly woman performing oral sex on Alan were blurred in order to reduce the rating from a "18" to a "15". This version was also released on DVD.
