Reni Santoni, an actor known for his role alongside Clint Eastwood in “Dirty Harry," has died. He was 81.

Santoni died while under hospice care on Saturday in Los Angeles following years of health issues that plagued the screen and stage performer, Santoni’s close pal, TV writer-producer and musician Tracy Newman, told Fox News.

"He passed away on Saturday, August 1. He was the funniest man I've ever known," Newman wrote in a statement. "Besides being a terrific actor, he was a legendary improviser. He will be missed."
