Kevin Smith, who helmed last year’s box office flop ‘Cop Out,’ recently appeared on the ‘WTF with Marc Maron’ podcast and expressed his dismay with working with main actor Bruce Willis, the Daily Mail is reporting. The director said he wasn’t pleased with the actor’s commitment and attitude while they shot the film. Smith declared that one reason the movie only grossed $44 million in North America against a budget of $37 million because working with Willis was difficult.

While Willis later scored hits with his two other action films last year, ‘The Expendables’ and ‘RED,’ Smith asserted that “I’ve never been involved in a situation like that where one component is not in the box at all.” The director also said that besides being hard to work with on set, Willis even refused to pose for promotional pictures.

After Smith ended his rant about Willis, he happily spoke about one of ‘Cop Out’s other stars, Tracy Morgan. Smith said he would lay down in traffic for Morgan, and “Were it not for (Tracy), I might’ve killed myself or someone else in the making of that movie.”
