Cops arrested a creepy Cajun crab fisherman for stalking Tatum O'Neal in the Louisiana swamps, where she's shooting "The Scoundrel's Wife" with Tim Curry and Julian Sands. Trouble brewed when a 38-year-old guy -- described as a weirdo who paints alligator eggs -- hired on as an extra and started passing notes to Tatum through folks on the set. Cops jailed him for stalking after he handed a note to a crew member and said threateningly: "Tell Tatum I mean business!"
