In theater, it is fixed throughout, and for some less intimate spaces, an actor will have to perform bigger actions to ensure clarity. The challenge here is to still be honest with the actions whilst performing these big actions.
For film, the performance can be varied throughout the movie. An action can seem to happen up close right in front of your face (POV shots), or it may happen so far away (cinematic wide shots), and therefore, the actor will have to be conscious of this when they perform.
Therefore, although the same approach may be used for an actor to prepare for a role, however, the craft of presentation is different. The best is to learn and get the best from both worlds and apply accordingly.
