Syfy's newest creature feature is amassing yet another pop-culture cauldron of familiar names.

The network's upcoming Bigfoot - which already stars the previously announced power team of Danny Bonaduce (The Partridge Family) and Barry Williams (The Brady Bunch) - is adding the following actors: Howard Hesseman (Head of the Class), Sherilyn Fenn (Twin Peaks), Andre Royo (The Wire), and rock legend Alice Cooper (School's Out). Bruce Davidson is directing.

When Bigfoot is discovered in South Dakota, two life-long rivals (Williams and Bonaduce) battle to capture the creature - one to exploit it and one to save it.

The movie will debut later this year
