ELI5: What do producers of movies do?

Also what is the difference between an executive and regular producer?

Producers organize the making and selling of a movie.  They find scripts, hire directors, co-ordinate with movie studios, fund the movie, deal with insurance and copyright, and do the marketing.  They are the backbone of the movie.

Usually, executive producers fund the movie by either directly paying for it, or by giving the movie resources such as a film studio.
