Question

When do you say "which" (e.g. movie, song etc) and when "what" (movie, song etc.) in English ?

Answer 1

What is asking specifically what the movie is when there are no options to choose from. Which is when there are options (e.g. 3 movies) to choose from.

Answer 2

When you are asking for a specific song or movie, they are pretty much interchangeable, although "which" is probably more grammatically correct.

Answer 3

And we wonder why people who don't speak the language throw up their hands in frustration(plus a few well-chosen expletives!) In this case,"which" and "what" are interchangeable,wheres "who" and "whom" are not although people often confuse the two

Answer 4

You say "which" when you are offering a set (or list) of things for the other person to pick one from. For instance: "Which dress do you like, the red one or the blue one?"

You say "what", like when asking an open-ended quesiton, like: "What is that movie with John Travolta and Samuel L. Jackson, you know, the one where they're both hitmen?"
