According to Murray, even now, “When I see him, I’m like: ‘I’m sorry, I wish I’d done that Clint, I’m really sorry.’ He’s certainly well over it. He’s a very resilient fella.” All that can be done now is to mark this one up as a movie that could've been. For now, check out Bill Murray's best movies here, none of which contain Clint Eastwood

The “Groundhog Day” actor regrets the decision so much that he still brings it up when he sees Eastwood, 94, around Hollywood. “And when I see him, I’m like: ‘I’m sorry, I wish I’d done that Clint, I’m really sorry,'” Murray concluded. “He’s certainly well over it. He’s a very resilient fella.”
