What movie role do Bill Murray and Johnny Depp have in common?

There is a movie that was made in 1980 called "Where the Buffalo Roam", starring Bill Murray as Hunter Thompson! The review at imdb.com says, “Now the first thing that struck me, was Murray´s incredible performance: He is 100% Hunter S. Thompson, the way he moves and talks. You can actually see how much Johnny Depp copied his acting in ‘Fear and Loathing’."

Got it, Mozart! My team missed this one tonight. We guessed Ebenezer Scrooge, but Murray's character wasn't even named that in "Scrooged!" and Depp never played him, so...
