>>hypothesis that people are more likely to watch movies with multiple superhero characters<<

If you're testing for "more likely" then what is survey data going to tell you? Because for that hypothesis, all you need are some statistics: (sales) for [five-to-ten different single superhero movies], versus (sales) for [five-to-ten different multiple superhero movies], where (sales) = theater tickets + video purchases + downloads

That's really about as close to an apples-to-apples comparison as can be done. You'd probably want to select the movies based on an arbitrary rule, like "ten most recent" or whatever, and you would want a big enough sample size to account for the fact that some superhero movies are way way more popular than others.
