“When Katie [Holmes] showed up on screen, there was a collective groan." These were the words of one insider who attended the Sundance Film Festival screening of The Son of No One.

The film stars Al Pacino and Channing Tatum, and was screened before audience members and industry insiders Monday.

Katie plays the wife of Tatum’s character and one source says she was “completely miscast.” Tatum plays a police officer based in Queens.

Several walked out of the screening before the film was over, though a statement released says this was due to a mistake made by the projectionist (the house lights were turned on too early).
