10 More Movie Mistakes You'll Never Unsee

10. A Switch Is Missed But The Lights Go Out Anyway - Grease

This may be the same weird picture that also contained a car flying off into the sunset and whatever was going on in that Beauty School Dropout number, but that still doesn't exactly explain how the lights managed to find a way to go out at one point in Grease without someone even making contact with a switch.

With the film taking place quite some time before folks were able to dim a room using only their voice, the visual of Vi going to press her elbow on a switch in the diner moments before that aforementioned Beauty School detour has left a number of T-Birds and Pink Ladies scratching their heads over the years.

As Joan Blondell's Frosty Palace waitress leans against the wall in hope and completely misses her target, instead of trying to go back and redo the blunder, the folks behind the project decided "meh, that'll do" and whacked the clicking sound effect over the top of the surreal sequence that then saw the lights suddenly go down.

Yet, everything from the awkward pause as Vi and Didi Conn's Frenchy wait for their visual cue, to the speed in which the bizarre occurrence is skipped over only adds to the charm of this entire 1971 classic.
