A key element in a movie is the chemistry between its main characters, and in many cases, the main acting duos seem too different from each other to work well on screen – and to everyone’s surprise, these actors turned out to have great chemistry. Throughout film history, there have been acting duos that have had such good chemistry on screen that they worked together in more than one project, and in many cases, actors have such matching energy or similar acting styles that they are guaranteed to work well together. In other cases, of course, acting duos have been so bad that they completely ruined the movie.
