Director: Jaume Collet-Serra

Writer: Oliver Butcher, Stephen Cornwell

Stars: Liam Neeson, Diane Kruger, January Jones, Aidan Quinn, Bruno Ganz

Liam Neeson elevates the proceedings considerably, but Unknown is ultimately too derivative -- and implausible -- to take advantage of its intriguing premise.

Main Cast


  • Tim Robey (Daily Telegraph)

    Scene by scene, the movie is clunky and laughable, but it's certainly never dull.

  • Peter Bradshaw (Guardian)

    A nifty final twist, but it is so joyless and heavy-handed I found it impossible to like. | Full Review...

  • Nigel Andrews (Financial Times)

    There are holes in the plot, but the film skips over them.

  • Philip French (Guardian)

    Enjoy it and then forget it...
