The movie business is a minefield of bad ideas. But someone needs to deactivate this one before it blows. At yesterday’s Peabody Awards gala, Saturday Night Live honcho Lorne Michaels hinted to The Hollywood Reporter that he was having “discussions” about a feature-length version of MacGruber.

Now, let’s take a step back for a second. This may never happen. I’m sure Michaels considers many such horrible ideas — many of which, sadly, make it onto the air every week. But a movie based on a sketch that wasn’t even mildly funny the first time it was on the show is just plain doomed. Doomed, I tell you!

For the uninitiated, MacGruber is Will Forte’s “wacky” mullet-haired riff on resourceful ’80s TV action hero MacGyver. He’s a clueless doofus who always has 10 seconds to stop a bomb from detonating using everyday objects. The gag is, he always gets so preoccupied with something else that he doesn’t save the day and the bomb goes off. Apparently, this is the kind of material that gets you a Peabody these days. Trust me, it’s even more painful than it sounds (add the occasional Pepsi tie-in and it’s also shameless). But if Michaels and Forte think this is their ticket to Wayne’s World-type box office gold, they’re also delusional. The skit barely manages to eke out 90 seconds of material, nevermind 90 minutes. See for yourself…

Let me play Hollywood oddsmaker for a second and predict that the domestic gross of MacGruber: The Movie falls somewhere between Tim Meadows’ The Ladies Man ($13.5 million) and A Night at the Roxbury ($30 million). And if it somehow manages to come out on a holiday long weekend, maybe it sneaks its way up to It’s Pat kind of money. Who else thinks this is a bomb waiting to happen? What do you think is the worst SNL flick ever?
