ELI5: Why are there 3 or 4 studios/production companies listed at the beginning of movies? After a major studio there will be several others (ABC Films, XYZ Pictures). Do the major studies need "help" making movies?

So you've got 5 main concerns regarding any movie project:

Who's actually making the film?

Who hold the rights to the film?

Who's lot/studio are you shooting in?

Who's paying for the film?

Who's distributing the film?

Each of these areas can involve a separate company earning it a production credit at the start of the film.
