As far back as last July (at Comic-Con in San Diego), Whedon described the project as "a horror film to end all horror films." All other details, including loglines or any description of the plot, are being kept closely uner wraps.
Nothing he touches is bad...nothing.
Drew Goddard, formerly a writer/collaborator on the Whedon-created "Angel," co-wrote the script with Joss and will make his directorial debut on the film. Whedon will produce.
"Cabin" is the first project to be greelit by new MGM motion picture head, Mary Parent. Parent is quoted calling the script "one of the most original and clever scripts I've ever read."
Of course it is, Mary...it's got Joss' fingerprints all over it. Here's hoping the project doesn't go the wasd of "Goners" or "Wonder Woman." As a horror-phobe, I'll start mentally preparing myself to go see it now.
