Parent Trap, The (1998) - Nice Catch, Annie?
Find the part in the movie when the twins are fencing. We know that Annie's outfit is completely white, and Hallie's outfit has green on it. The girl in all white, Annie, catches her sword after it flies into the air. Someone says, "Nice catch," in an English voice. Then someone says, "Thanks," in an American voice. It should obviously be the other way around.
