A student asks: “Is there a difference between see a movie and watch a movie?”
Yes, there’s a tiny one!
If I say “Let’s see a movie tonight” – it implies we’ll go to the movie theater.
If I say “Let’s watch a movie tonight” – it means we’ll watch a movie at home.
However, when asking “Have you seen (a certain movie)?” – we always ask “have you seen?” and not “have you watched?”
In this case it doesn’t matter if the person saw it in a movie theater or watched it at home; they could reply “Yes, I’ve seen it” or “No, I haven’t seen it.”
Hope this helps! Thanks for your question.
