I tell ya dues..the Dick Van Dyke Show has 6 names listed under producer. One of the big sitcoms nowadays,Ghosts has 37. THIRTY SEVEN!! You would think having all those producers might cause a problem!!! (them not agreeing on something)
Listing cast members as producers indicates they share a part of the show's profits. Like say Brad Pitt getting 5% or some such. So somewhere along the line, each of those producers share some of the revenue.
