Revealing mistake: When Cher is robbed and she calls her brother on a payphone, she doesn't put any money in and she doesn't press enough buttons to be using a calling card.
Clueless (1995)
1 revealing mistake - chronological order
Directed by: Amy Heckerling
Starring: Paul Rudd, Brittany Murphy, Alicia Silverstone, Stacey Dash
Other mistake: When Josh and Cher are driving home from a party, they show a shot of the car. It's a blue sports car that passes a Hertz car rental sign. When Elton is driving Cher home from the party in the Valley, they show the exact same shot of the blue sports car passing the Hertz car rental sign.
Trivia: Writer/director Amy Heckerling was in the middle of writing the script when she saw Alicia Silverstone in an Aerosmith video on MTV, and immediately knew that was who she wanted to play Cher.
