Winston, played by Ernie Hudson, was originally a much bigger part. But the rewrite that took place after Eddie Murphy dropped out reduced the role so they could better flesh out Bill Murray's character.

Hudson wishes that he got to do more in the movie, he said "I love the character and he's got some great lines, but I felt the guy was just kind of there. I love the movie, I love the guys. I'm very thankful to Ivan for casting me. I'm very thankful that fans appreciate the Winston character. But it's always been very frustrating-kind of a love/hate thing, I guess."
