What did they do?

I just finished watching “ENIGMA”

It ended with a big “Produced by Mick Jagger and Lorne Michaels.”

I thought Michaels was producing that subpar trash SNL and Jagger was on tour with the Stones.

What did these 2 actually do to get this film made? Put up money? I thought that was the Executive Producers and the Co-Executive and all the other executive producer titles job.

Seriously, what the hell do all the “PRODUCERS” do?

I realize that there has to be one or two actually there to make sure it gets made and to keep the director and actors happy.

What did Jagger and Michaels do to be called “producers” on this film. Is it just more hollywood nonsense to get more people interested in it?
