Does it violate the post about asking for identification of movies?
Will my question be closed for being off topic?
No and no. first-appearance questions are not identification questions and are on-topic. If they were banned, the tag description would contain the following message, jsut like the other ID tags:
NO LONGER ON TOPIC. DO NOT USE. IDENTIFICATION QUESTIONS WILL BE CLOSED AS THEY ARE NO LONGER SUPPORTED.
Furthermore, identification questions are closed very quickly here, usually in a matter of minutes. As of right now, it's been six hours, and nobody has voted to close your question. I don't believe anyone will.
I can't say for certain why your question was downvoted. Users are under no obligation to explain their downvotes, for a variety of reasons. However, it would not have been because your question is off-topic; downvotes are not close votes. My only guess is that the downvoter decided your question was "not useful", which is a valid downvote reason. (For the record, I do not believe your question is "not useful"; it could be interesting to see how quickly Hollywood began integrating video technology into its plotlines.)
