The Out-of-Towners (1970 Arthur Hiller)

It looks to me like Neil Simon's having a dig at his New York - pollution, muggers, overworked police, strikes... as well as the airline industry (anyone who's ever been rerouted on a plane will wince with empathy). Poor old Jack Lemmon and Sandy Dennis get unlucky at every turn and ultimately turn their back on the city. It's not and never has been actually that funny, and reminded me more than once of Scorsese's After Hours.
