He also died within the last few days.
The role that that is being mentioned was Blake Carrington on Dynasty but my favorite was his portraying Alvin Dewey in "In Cold Blood." Alvin Dewey was KBI agent in charge of Clutter murder investigation. Alvin Dewey was a dogged investigator and Forsyth portrayed him that way. He was one of the good things in a very over rated movie.
Forsayth was also used by Hit chock in two movies. Forsayth was not used anywhere as often as Cary Grant or James Stewart but I thing Hitchock valued him.
