I looked at Martin Charnin's profile in ibdb. It validated what I have always assumed: one of the luckiest people alive. Heck, he is even married to Shelly Burch, from the original cast of Nine.
Why luckiest:
1. Annie is the only thing i his resume that is in any way impressive IMO
2. When Annie opened, there were articles that essentially stated that Mike Nichols was responsible for the success of the show; that he came in, tore it apart, etc. Nichols, always a class act, never responded to inquiries; despite Annie being the monster hit of the season, come Tony time, Charnin lost for director to Gene Saks, who directed I Love My Wife, a delightful and straightforward show that was never a big hit. To this day, I recall it having a cast of four, although that was probably not the case. Big extravaganza, huge hit, vs. little show...for direction??? After the Tony's, there was some reporting that he lost because voters did not actually believe he directed it based on the gossip of the day.
So iMO -- and i am definitely being snarky, but I have never liked him from anything i have read or seen on an occasional TV show -- he was sort of a one-hit wonder who views Annie as his place in theatre history.
