Boys' Night Out is a 1962 American romantic comedy film starring Kim Novak, James Garner, and Tony Randall, and featuring Howard Duff, Janet Blair, Howard Morris, Patti Page, Anne Jeffreys, Jessie Royce Landis and Oscar Homolka.

The picture was directed by Michael Gordon and was written by Ira Wallach based on a story by Arne Sultan and Marvin Worth.

Their bachelor friend arranges for a "kept woman" who is in reality a sociology student studying the fantasies of contemporary American men.

Three married men, George, Doug, and Howie, and divorcé Fred are friends who commute to work from Greenwich, Connecticut, to New York City on the same train.

Seeing Fred's philandering boss, Mr. Bingham, with his mistress sets the men to fantasizing about sharing the expense of an apartment in the city as a love nest.

Fred rents a luxurious suite from Peter Bowers, who is desperate to find a tenant because the previous occupant was a highly publicized murder victim.

The boys are delighted; each tells his wife that he is taking a course one night a week at The New School for Social Research to improve his mind so he can stay in New York overnight.

Unbeknownst to the men, Cathy is actually a sociology graduate student writing her thesis on the "adolescent fantasies of the adult suburban male."

In the end, the wives become suspicious, and on the advice of Fred's mother, Ethel, hire private investigator Ernest Bohannon to find out what is going on.
