Nope they don't have to have feelings for each other
When two actors have to kiss in a movie do they sometimes have real feelings for each other?
It is possible that they could, but most times probably not.
I think it would be just another job for them. Although romance has happened for some, like Brad Pitt and Angelina Jolie, but I doubt that's the norm.
Maybe because I saw this one movie and now they are actually dating
