ELI5 the Exact Job of a Hollywood Movie Producer

Just how much shit do they have to go through and why is it that they seem to get a lot the credit for the film/musical?

Simply put, a producer, like Scott Rudin (who has produced No Country For Old Men, Greenberg, The Social Network, etc.), is the person who first reads the original screenplay, decides it's good enough to be made into a film, gathers up funding from various production houses and investors, and recruits the director and other very important figures to work on the film. Basically, the producer is very often the jumpstarter of the film, helping to bring everyone together to create it.
