Victor, Victoria (1982) Julie Andrews, James Garner
Okay, really--I haven't watched this movie.  I swear. 

 But last night I was at an 80's themed party with my wife, and throughout the night the DJ was playing a compilation of 80's movie trailers on a huge screen behind the dance floor.  This movie comes up and there's a scene of Julie Andrews trying to smoke what looks like a lancero and coughing her head off.
