Question

I want to write at "what time do you finish the film?" in french.

is this how you write it?

¨¤ quelle heure finis-tu le film?
E.G.
I would have said: "à quelle heure finiras-tu le film."
or, in formal: "à quelle heure finirez-vous le film."

Because the English says "what time DO you FINISH the film?: (in the present time)
à quelle heure finis-tu (finissez-vous) le film?

E.G. finiras-tu is perfect for "WILL you FINISH" and "finirez-vous" for the same English, formally.
