Joel McHale has shared his experience playing the son of the late Robin Williams in the recently released comedy film "A Merry Friggin' Christmas."

"It was something I always dreamed of and when I got to do it, it couldn't have been a better experience," McHale told ABC News adding that Williams was "so amazing and so giving and kind and cool" and "everything you want in meeting one of your heroes."

McHale described the way the world loved Williams "pretty rare" and said attending his funeral was "one of the sadder things" he has been to in a long time.
