Blame It on Rio is a 1984 American romantic comedy film directed by Stanley Donen, based on the 1977 French film Un moment d'égarement, and starring Michael Caine, Joseph Bologna, Michelle Johnson, Valerie Harper, and Demi Moore.
Matthew (Caine) and Victor (Bologna) are good friends and business partners who live and work in São Paulo, Brazil. Victor is going through a nasty divorce from his wife, and Matthew's relationship with his wife Karen (Harper) has turned frosty. The two men and their families are headed off to a vacation in Rio de Janerio, but at the last second, Karen says she isn't going with them, but prefers to go off on a vacation by herself.
That leaves Matthew, Victor, Victor's 17-year-old daughter Jennifer (Johnson), and Matthew's daughter Nikki (Moore). The foursome heads off to Rio together. Soon Victor discovers that Jennifer, who is underage, slept with an older man. Furious, he asks Matthew for his help in catching the older man. There's just one problem: That "older man" is Matthew.
Stanley Donen's last theatrical feature.

- Bookends: In the first scene Karen surprises her husband unpleasantly, by telling him just as they're leaving for the airport that she isn't going to Rio with him, she's going to Bahia. In the last scene she surprises him again, by saying she's going to Bahia but he isn't going back to São Paulo, he's going to Bahia with her.
- The Capital of Brazil Is Buenos Aires: All women are topless at the beach and surrounded by monkeys, parrots and toucans.

Matthew: And being unfaithful to my wife will get me that way fast.

Karen cheating on her husband, with her husband's best friend. Heck, Matthew having sex with his daughter's best friend, which the daughter actually sees happening (at the beach). Everybody gets past this at the end and they all make up.

- Godiva Hair: Oddly enough, during the (in)famous scene of Nikki and Jennifer being topless, while Jennifer's top is completely exposed, Nikki has her hair conveniently covering her breasts.
- How Do You Say: Eduardo Marques uses this stock phrase, when he meets Victor and Matthew at the produce market.Eduardo Marques: You are, how you say, the queer couple?

- May–December Romance: Matthew has an affair with Jennifer, who could easily be his daughter. As in, she's actually his daughter's friend and are of the same age.
- Ms. Fanservice: Jennifer spends pretty much the whole movie either naked, semi-naked, or scantily clad. To a modern audience it could come off as Fan Disservice and Squick since it's established that she's underage (and Michelle Johnson actually was underage).
- No Fourth Wall: Both Matthew and Jennifer serve as narrators, addressing the camera directly as they relate the story.
- The Reveal: Near the end of the movie, after Karen comes to the rental house, it's revealed that she and Victor are having an affair.

- Smoking Hot Sex: Victor manages to pick up a woman who isn't his friend's daughter. They are shown smoking cigars on the hotel balcony while clad in bedsheets, after a night of passion.
- Split-Screen Phone Call: A quite frosty one as Matthew calls Karen and gets a cold reception, after he arrives in Rio.
- Tan Lines: The topless extras at the beach mostly have tan lines, thus showing that they aren't usually topless.
