Overtime it became “the film look”. One hundred-ish years later we still record TV shows and movies in it that we want to look “good” as opposed to “fake” like a soap opera.
And it’s all happenstance. The movie industry could’ve moved to something higher at any point other than inertia. With TV being 60i it would have made plenty of sense to go to 30p for film to allow them to show it on TV better once that became a thing.
