In "The Hangover," a blowout Las Vegas bachelor party turns into a race against time when three hung-over groomsmen awaken after a night of drunken debauchery to find that the groom has gone missing, and attempt to get him to the alter before his wedding day. Heather plays a stripper in the film.

Graham had her breakthrough role in 1997's Boogie Nights as Rollergirl, an underdressed, oversexed, coke-snorting young porn actress.
