Not only opposite sex! When I was a kid everyone watched action movies with fit guys like Schwarzenegger or Stallone shooting some ridiculous-looking machinegun or rocket launcher while being topless for no practical reason what-so-ever and everyone wanted to look like them! Granted, now I'm not into actions and don't watch modern superhero movies at all but I suspect people still like to associate with heroes of the movies they watch, so I wouldn't enjoy watching average fat American John McSmith acting as Rick Deckard that much...
