I feel surrounded by love and am forever grateful to each and every one of you.”

A post on the official “Highlander” TV series Facebook page also paid tribute to the former actor.

“It is with great sadness that we acknowledge the passing of Stan Kirsch,” the post read. “He brought a sense of humor, kindness and youthful enthusiasm to the character of Richie Ryan for six seasons.”
