I started with Sidney Poitier and Ruby Dee and Lou Gossett, Jr. and the rest of the wonderful cast of 'A Raisin In The Sun.' We were directed by the great Lloyd Richards. The play was written by the wonderful Lorraine Hansberry, and it was produced by Phil Rose. That's where my start was, so... not a bad way to start.
If you take the '70s with Blaxploitation pictures, there was a proliferation of black-content films and motion pictures, television, stage plays and so forth at a time when Hollywood was in trouble financially, and it was cheaper to do black films to keep the lights on until they could reestablish themselves.
