1. The actor films the movie- in English, this would make me think that either a) the actor is also the director (ex: the director is also acting in the movie) or b) the actor is holding a video recorder and is literally filming the movie while other people are acting. If you want to say that he has a role in the movie, then you can say 'the 'actor is playing in the movie.' You cannot use 'play' and 'film' interchangeably here. They have different meanings. In English, 촬영 can only refer to filming or shooting (like in photography).
