Filmed in 12 days in Santa Monica, the production features Alexis Denisof (of “Buffy the Vampire Slayer” and “Angel” fame) as Benedick, the man who treats marriage like a disease he hopes he’ll never catch, and “Alias” and “Angel” alum Amy Acker as Beatrice, a equally adamant bachelorette. In accordance with the Laws of Shakespearean Courtship, they loathe each other until they love each other.

Other cast members include frequent Whedon collaborator Nathan Fillion, formerly of “Firefly” and “Dr. Horrible’s Sing-Along Blog” and currently the titular star of “Castle,” Fran Kranz from “Dollhouse”, Clark Gregg from “Iron Man,” and Reed Diamond from “Moneyball.” The news release for “Much Ado” says to expect that “the film should be completed by early spring and headed for the festival circuit, beacuse it is fancy.”

“Much Ado” is the first production by Bellwether Pictures, a micro-studio created by Whedon and Kai Cole. Whedon just completed principal photography on “The Avengers,” a Marvel comic book flick whose protagonists (probably) do not burst into song at the laundromat.
