John Mahoney, whom you probably...

...know best from his role as Martin Crane, Frasier's father on the sitcom of the same name, died at age 77.

But the longtime resident of Oak Park (did you know that?) who was born and raised in England (he deliberately shed his British accent in the U. S. army -- who knew?) also played a troubled CEO on the HBO show, In Treatment. I didn't think Mahoney was particularly believable in that role -- I thought he was a little too old to play a CEO; shouldn't that character have been in his forties or fifties? But the series itself, which ran from 2008 to 2010, just might be the best show you've never heard of.
