Charnin's daughter, Sasha Charnin Morrison, announced her father's death Sunday. She said Charnin passed away days after suffering a minor heart attack on Wednesday.
He was a keeper of the "Annie" flame, protective of what he created with songwriter Charles Strouse and book writer Thomas Meehan. The 1977 original won the Tony for best musical and ran for 2,300 performances, inspiring tours and revivals that never went out of style.
Charnin also played Big Deal in the original 1957 production of "West Side Story."
