Deliberate mistake: At the end of the movie when everyone is on the bridge, the one female cop roundhouses the bad guy, who is clearly a white male in his 50's, but his stunt double is an Asian man (with different colored hair). They use the same stunt man a few other times for people he doesn't even look like.
Deliberate mistake: When Jackie starts the rally car in the desert, he does not push in the clutch even though it is a standard transmission.
Answer: It's quite possible because most movies use dubbing (or "looping") as part of the post-production work to enhance the quality or fix minor sound problems. Sometimes a different actor's voice is dubbed over a minor on-screen character.
