A good friend of mine told me that a year or so ago, he'd met Rowdy Roddy Piper (in some Lancaster baseball skybox) and said they'd talked about making this movie. In my friend's words: "He basically was asked to do it with no script and was offered if I remember right $10,000. So he signed the papers then he read the script. He said his wife was pissed." Who knows if Rowdy was telling the truth or not, and I hope he's remembering the money amount wrong, but I think it's funny if his wife was pissed after she'd read the script.
He ALSO said that Rowdy told him the scene where he signs the contract he accidentally signed it "Rowdy Piper" instead of "Sam Hell(man)." I tried to see the signature but couldn't, but the second time he signs it clearly looks like he's dotting something, like the "i" in "Piper."
