Kate Beckinsale joined the legions of stars debuting films at the Toronto Film Festival, as she walked the red carpet Monday night for her new movie, 'Nothing But the Truth.'

In the film, directed by Rod Lurie, Kate plays a Washington D.C. reporter who reveals the name of an undercover CIA operative in a story, and gets thrown into the slammer when she won't reveal her source.

The film co-stars Matt Dillon, Angela Bassett, Vera Farmiga, David Schwimmer, Noah Wyle and Alan Alda.
