A bit surreal hearing a character say a line in a foreign language during an English movie... and understanding exactly what he said.
Balthazar: Tau fa ho leng.
Old Chinese lady: Oh, you speak Mandarin!
Me: *leaning over to friend & whispering* That's not Mandarin, that's Cantonese!
Balthazar: *whacks the old lady into a wall* That was Cantonese, Horvath.
*grins* I'm by no means a pro at either of the languages but I know in Mandarin it would've been "Ni de tou fa hen mei" ;)
