As difficult as it is to imagine, the relationship between the 2 actors in one of the most romantic movies of all time was actually extremely strained. Patrick never tried to hide the fact that Jennifer annoyed him. In his memoirs, he later wrote that Jennifer was a really unprofessional actress who constantly ruined the filming process.

Regardless of whether or not these actors are friends or enemies, they managed to stay professional enough to play their roles in such a way that their friendships seemed real to the viewers!
