Are you ready for some major disaster film effects? Were you disappointed that there wasn't more destruction when the Golden Gate Bridge broke in half on Eli Stone (I was.) Then you, like me, will be pleased to hear that David James Elliott is starring in a four-hour mini-series called Impact. Producers are promising lots of action and Charlton Heston-like epic disaster. Okay, maybe I added the Charlton Heston adjective, but at $13 million, the guys at Muse Entertainment, Jaffe/Braunstein Entertainment and Tandem Communications aren't skimping.

Casting David is a plus for starters. The former JAG star has a nice balance of serious and tongue-in-cheek, so hopefully he'll keep Impact from getting too cheesey. The story, however, does have Velveeta potential.
