Katie Holmes may have been knocked down, but she's far from out.

First her Kennedy miniseries found a home on fledgling cable network ReelzChannel (it's slated to premiere April 3) now her crime drama, Son of No One -- which premiered at the Sundance Film Festival to mixed reviews -- has been purchased.

"I always knew the film would sell because it's a good movie," producer and sales agent Cassian Elwes tells

That's not to say the actress -- who only has a few scenes in the film, which stars Al Pacino and Channing Tatum -- didn't feel the sting of the harsh critique.

According to Elwes, Holmes, 32, "loves the film. She was very upset by this attack."
