“Proof” star Callum Blue and Nadine Velazquez (“Major Crimes”) are starring in the indie drama “The Charnel House,” which has started shooting in Cleveland.

The cast also includes Makenzie Moss (“Steve Jobs”) and Erik LaRay Harvey (“Boardwalk Empire”). Producers are Sandra Siegal through her Siegal Entertainment banner and MJ Films’ Mark B. Johnson, who are re-teaming after working together previously on Katie Holmes’ comedy “Miss Meadows.”

Craig Moss directs from a script by Emanuel Isler and Chad Israel. Executive producers are Daniel Diamond, Capital Fund’s Warren Ostergard, Blair Hahn and Michael Brickman along with Jim Jacobsen.

Blue plays an accomplished British architect who finally achieves his dream of converting the long-abandoned Fairmont Meat Company slaughterhouse into ultramodern lofts. His family and tenants will be exposed to a decades-long mystery that cannot be covered up by the building’s high-tech makeover.

Velazquez portrays his wife and Moss plays the couple’s behaviorally-challenged young daughter.
