10Hz is 10Hz, eh.

Now I enjoy spotting filmmakers' errors in continuity or geography as much as the next guy, but if I EVER utter anything this anal upon exiting a movie theater, you have my permission to slap the living piss out of me.

From the Internet Movie Database goofs page for The Bourne Supremacy:

Errors in geography: In the opening minutes of the film, Bourne has his nightmare in Goa and goes to the bathroom. We hear the fluorescent lamp ballast (choke) buzzing at 60Hz, however if Bourne is in Goa, India like the film says then it should be buzzing at 50Hz.

For the love of God, WHO NOTICES THIS? It's a MOVIE! Let it go, people.
