Jon Polito died last Thursday night - you will probably recognise him from many of the Coen brothers films most prominently Miller's Crossing - which I watched for the first time last year.
He has over 200 credits on IMDB. Brad Gullickson sums up perfectly his career on the One Perfect Shot website linked below.
“I’m talkin’ about friendship. I’m talkin’ about character. I’m talkin’ about – hell. Leo, I ain’t embarrassed to use the word – I’m talkin’ about ethics.” As the upstart gangster looking to expand his tiny corner of the city into a proper empire, Jon Polito excelled in portraying the desperate criminal moralist, Johnny Caspar.
