Blame It on Rio is a 1984 American romantic comedy film directed by Stanley Donen and written by Charlie Peters and Larry Gelbart based on the 1977 French film Un moment d'égarement [fr],[3] starring an ensemble cast, including Michael Caine, Joseph Bologna, Michelle Johnson, Valerie Harper, Demi Moore, and José Lewgoy.

As soon as Matthew says that the water is warmer than he anticipated, Jennifer passionately kisses him, which Nikki witnesses, and the two proceed to have sex on the beach.

Jennifer attempts to commit suicide with an overdose of birth control pills, but survives and the incident brings all of the friends closer together, but the men constantly object about each other's sexual misconduct.

"[4] The Canberra Times described Blame It on Rio as "one of the worst movies ever made and definitely the most banal piece of rubbish to have Michael Caine's name on the credits—and he has quite a few bombs to his credit.

A disturbed girl is using sex to play mind games with a middle-aged man, and the movie get its yuks with slapstick scenes...What's shocking is how many first-rate talents are associated with this sleaze.

"[9] Chris Chase ranked the movie in this new breed of exploitation films (Angel, Risky Business, Reckless) addressing the topic of teenage sexuality.

The consensus summarizes: "It isn't clear who is most culpable for this creepy comedy's sheer wrongness, but its smarmy laughs and uncomfortable romance will leave audiences feeling guilty long afterward.
