Not sure if this has been answered elsewhere but John Lithgow brilliantly played a horrid piece of work in Season 4 of Dexter.Why did John Lithgow never play more bad guys? He was deliciously nasty in Cliffhanger.
The problem is you need to watch 3 seasons of Dexter to get there. FAMOUSLY THERE WERE ONLY FOUR SEASONS STOP AT THE END OF SEASON 4
