Something that non-cinephiles donโt know about movies and TV: In most films and shows, especially if they have any actors with recognizable names in them, if the actorโs face is not actually in the shot there is a very good chance the actor โinโ the scene was not on set when it was filmed.
The reason is that โnamedโ actors are very expensive, and the more you can avoid having them work the less costly the production โ and often, the less hassle.
So if you see the โactorโsโ hand? Likely not them. The back of their head? Likely not them. Hear them talking but donโt actually see them? Probably dubbed in later.
If you donโt actually see an up-close shot of the actorโs face in a scene, there is a really good chance they were not present at all when the scene was filmed.
