Did.
what ..... you see at the movies tonight? a). Do. b). Did c). Does
either A or B ... Depending on tense.
If you're in the theater, watching the movie, it would be "Do".
After the movie, it would be "Did".
Mess with the teacher's mind.
Does is immediately out of contention.
Did is past tense. Unless you are going back to class after the movie, it's not a candidate.
Do is the only one left.
If you were actually watching the movie and were asked the question, a verb phrase indicating present action would be more appropriate, i.e., are you seeing.
Will you see would also be acceptable.
I assume you are getting the point.
