Well, I'll start with what B movie REALLY meant, at least originally. As someone who studied Film/TV in community college, Cal State, even UCLA, that really relates.
The name B movie came about when there was a really active producer at one of the studios whose last name started with 'B.' Couldn't find his name online. If he didn't make it, it wasn't a B movie. He'd use the old sets and costumes from other movies, he'd bring in actors whose stars were falling but were still well known who hoped this would start a comeback. He'd even give cameos to almost forgotten stars of yesteryear, which proved quite popular. Fan service was the name of the game. The budgets were smaller than usual, but they were released as being the same as films costing 5 times as much, at times they could be the top grossers.
Now, on to what eventually evolved. People think of B movies as being without A list actors. Perhaps that's where A list came from. What I will say is to be a B movie, it has to be made with the intent of fan service ahead of making a good movie. A young girl from Fullerton went to Hollywood and had supporting roles in a bunch of movies where she got naked. Major controversy in her family, being the daughter of a preacher/leader of the congregation. She was in films with names like 'Hard Bodies.' Without having seen any of these films or hearing any more titles, are you thinking of B movies?
Roger Corman and American International Pictures had this strategy of giving the theaters posters for films where the only work done on the idea is the poster. When the audiences asked when 'The Day the World Ended' was coming out, they knew that was one they needed to make. The only thing they knew was what the monster looked like, because they'd included the head on the poster. The finished film was cheesy, it was different, it was everything the audience had hoped for. Pure fan service.
What do you think? Is the movie below the purest of fan service? Those 4 women at the top that look like they're not wearing anything: Do you think they forgot to go to wardrobe at least once during shooting? Are you thinking B movie?
Nothing against fan service, nudity without being porno, etc., I could be talked into making something that's not G rated. But is it going to be a real bad movie, such as Asylum remaking all these major films while they're making the original and releasing their bad version of the same thing at the same time? And are you going to go see such a film?
