Well, yes. I chose this example quite deliberately, with the intent of leading into the context you describe. First, because it’s important to understand that film is a director’s medium, not an actor’s, because the actor (with very rare exceptions) has basically no control over how the footage is cut together during editing. The experienced film actor is very conscious that he or she is simply giving the director and editor raw material, a variety of choices and nuances across multiple takes, and must trust that they will assemble a coherent performance out of all these bits and pieces during post.
Further, it’s true that Kubrick wasn’t entirely honest with Scott as to the purpose of these takes (though this has been overblown quite a bit, similar to stories of Kubrick “abusively” directing Shelley Duvall during The Shining, which are just bullshit). And yet, even despite this, Scott remains committed to the performance from a technical, professional standpoint. While he turns up the silliness as requested, he nevertheless stays focused on everything an actor must do, playing his circumstances and actions against the other actors. Just because Kubrick asked him to go hammy, it doesn’t mean he threw out his actor’s toolbox.
So, yeah. That’s where I was going with this, but I was hoping people would actually go watch the movies as I suggested before I brought it up. Oh well.
