How is Film and TV acting different from theatre acting?

Film and TV acting is different in many ways from theatre acting. Firstly it is much more unforgivable, for example the cameras pick up much more of your facial expression as it is closer and more focused, this means it picks up any habits which a person might have. Actors/actress's have to compensate for this and use facial expressions in more detail (not over the top though) and work on any habits they may have. As the same scene may be filmed over a few different days continuity is crucial e.g an actor/actress must use the same facial expressions, vocal tone and gestures all the time which means you can't improvise like you can on stage (also the cameras must know where you are going to move so you definitely can't do something that is unexpected). There is much more waiting around and preparation before a shoot, therefore you have allot of patience.
A big difference is the positioning of the characters, on stage there is much more space so there is room to position yourself naturally, whereas on camera actors/actress's have to compensate for smaller shots by moving closer together and making gestures smaller.
Actors/actress's also have to be "in the moment" more as it starts and finishes very quickly, this is important as the camera picks up the persons emotions much more closely . Therefore being in the moment means that an actors emotions look more realistic and convincing.

Overall both acting styles vary massively so it is important to understand the differences between them and to know what is needed and expected of you as an actor/actress. Yet although they are both very different, some aspects are still similar e.g you still have to know your charcater and their emotions, you still have to project your voice more in film and Tv as the microphone has to pick up the sound, there is alot of preparation and work in both theatre and Tv/film.
