Darko Entertainment and Principato-Young Entertainment announced today that Rob Huebel (The Descendants), Paul Scheer (Piranha 3D), Riki Lindhome (The Last House On The Left) and Keegan-Michael Key (Due Date) are joining the cast of Hell Baby. The film marks co-screenwriters Thomas Lennon and Robert Ben Garant’s feature film directorial debut. They join the previously announced Rob Corddry (Hot Tub Time Machine, Warm Bodies) and Leslie Bibb (7500, Midnight Meat Train) in the film.

In the horror comedy “A young expectant couple moves in to New Orleans most haunted fixer-upper and calls upon The Vatican’s elite exorcism team to save them from a demonic baby. Lennon and Garant will portray that team.” The film is an original script from the multi-hyphenates Lennon and Garant, who have written nine feature films together including Night at the Museum, Night at the Museum: Battle of the Smithsonian, Taxi, Reno 911!: Miami, Balls of Fury, and The Pacifier. They are currently writing Rentaghost for 20th Century Fox and Ben Stiller.

Even if I’m not a huge fan of Lennon & Garant’s moneymaking screenwriting behemoths like Night At The Museum, I respect the frankness with which they address those paycheck projects (which pay them a lot) and the other, funnier, stuff they’re more passionate about. I find Lennon particularly hilarious on camera as well.

Hell Baby started filming today in New Orleans.
