Deliberate mistake: When Jim and Lauren are having their stargazing experience, it's clear that the pints of beer the monkey brings them are fake so that they don't get spilled.
Blended (2014)
1 deliberate mistake
Directed by: Frank Coraci
Starring: Adam Sandler, Drew Barrymore, Terry Crews, Kevin Nealon
Genres: Comedy
Other mistake: Since the vacation was supposed to be for Dick, Jen and Dick's five kids, the hotel suite kids' room should have had five beds, not four.
Trivia: When Jim and Lauren are at the store buying tampons and an adult magazine there is a cameo by 10 Second Tom - a character from 50 First Dates (another movie Sandler and Barrymore made together).
