In interview with the New York times Nicolas Cage described the movie as disappointing and said that the director Larry Charles didn't get a final cut
According to Nicolas Cage, director Larry Charles didn't get a final cut. Co-star Paul Scheer revealed in his 'Unspooled' podcast that the film was distributed by the company of Harvey Weinstein and Bob Weinstein, who were notorious for re-editing movies against their directors' wishes. To circumvent this problem, Charles had frequent discussions with his editor about what shots he needed. He purposefully limited the amount of footage shot and did a lot of in-camera editing as to give the Weinsteins less opportunity to interfere with the final product. This didn't stop them from re-cutting the film and giving it a limited release, however.
