Actor Johnny Brown, known for playing housing project superintendent Nathan Bookman on the massively hit show 'Good Times', has passed away at the age of 84.

Johnny's daughter Sharon Catherine Brown told TMZ that he was at his doctor's office in L.A. on Wednesday getting his pacemaker checked out, and shortly after he left he went into cardiac arrest and collapsed. He was taken to a nearby hospital, where he passed. She says the appointment was routine, so his sudden death was a shock.
