Drug abuse is a terrible thing, kids. It land you in jail, ruin your reputation and turn you from a busy character actor into an uninsurable pariah. Case in point: Crazy Tom Sizemore just got fired from pre-production on a flick called The I Scream Man -- and if you can't hold on to a job in a movie with that sort of title, then you're definitely living life a little too hard. I know his drug problems are entirely of his own creation, but I really do feel for the guy. He went from working with Michael Mann, Oliver Stone and Steven Spielberg -- to a public dismissal on The I Scream Man. Ouch.

According to STYD.com, Mr. Sizemore was fired from the upcoming horror flick and replaced by sometimes co-worker Michael Madsen. The reason for his dismissal? Another visit from the "drugs and jail time" fairy. It might sound like I'm cruelly mocking the guy, but the truth is I feel really rotten for Mr. Sizemore. Here's hoping he can right the ship, toss that monkey off his back and mount a small comeback of sorts. In the meantime, J.T. Mollner's The I Scream Man will go into production this summer with Madsen, Dee Wallace, Haylie Duff, Fred Ward, Judd Nelson and the entertainingly bizarre Crispin Glover as ... The Ice Cream Man. (Yes, it's a horror movie.)
