Did she film many times?
Fun fact.
This trick shot by Mary Tyler Moore in a 1962 episode of "The Dick Van Dyke Show" was actually made in one take.
It was intended for an expert pool player to film the trick, but to everyone's surprise, she actually got it. https://video.nostr.build/29d30dcab365f0e294862a6203790ab1fd461942cdd38b75b69ae56f5810f66e.mp4
