Producer vs. Director

[Carlhue]

Could someone explain it to me like I'm 5 what the difference is between a producer and a director?

I never bothered to find out, but these days I'm really curious.

From what I know, a director would be responsible for the whole picture of the film. It's someone that will decide if the scene was satisfying or ask to keep on retaking. I'm not quite sure about the producer, but I know there could be more than one.
