Continuity mistake: At the end of the movie when the girl and guy are boarding the submarine, the camera switches to a view where you can see an apartment complex in the background. If you look towards the top you can see someone standing at the balcony and then they move off towards the balcony door. In the next shot the person is gone.
Continuity mistake: In the first few minutes when they are travelling in the taxi, the sign on top of the taxi changes from width-ways (not very aerodynamic) to length-ways when they get out.
