Other mistake: In the scene when Hector Lavoe and his wife (Mark Anthony and JLo) are walking down the street in New York, on the right hand of the screen you will see a man taking a picture with his cell phone. The scene is supposed to be based in the 70's.
Other mistake: There is a scene where Miss Potter is in the Lake District beside a lake drawing. Across on the other side of a lake there is a red car driving along the road quite fast. This is in the cinema version.
