Fear and Loathing in Las Vegas (1998)

Factual error: The movie is set in 1971, but during the start of the motorcycle race several of the bikes are obviously early 90's Honda CR's and Suzuki RM's. You can tell this from the disc brakes on the front wheels of the bikes and the 90's style plastic fenders and bike colors. Bikes in the 70's generally had metal fenders and definitely no front disc brakes.

Raoul Duke: The store was closed, but the salesman said he could wait if we hurry. But we were delayed en route when a stingray in front of us killed a pedestrian.

Trivia: In the flashback where Johnny Depp takes LSD in the bathroom of a 60's bar, the hippy who starts to lick the LSD he dropped is Red Hot Chili Peppers bassist Flea.
