When Mischa Barton was unceremoniously killed off the teen soap, The OC; I think most of us thought this was her chance to transform her teen stardom into a successful movie career. So far that hasn't happened, and I personally doubt her latest role is going to do anything to change that. Variety reports Barton has signed to star in the psychological thriller Walled In. The story centers on "a demolition company rep who supervises the razing of a mysterious building and discovers horrifying secrets and past inhabitants entombed within its walls by a vicious murderer". Based on the French novel Les Emmeures by Serge Broselot, Barton will play the demolition company rep -- and is it just me, but when you think commercial demolition and construction, someone who looks like Barton doesn't exactly come to mind?

Joining Barton are Deborah Kara Unger (Silent Hill) and Cameron Bright (Juno -- you can catch Scott's TIFF review of that film here) and set to direct is French helmer Gilles Paquet-Brenner (Gomez and Tavare). This will be the first English-language feature for Brenner, who also helped adapt the novel for the screen. Barton has been piling on the projects lately, having signed for the caper film St. Trinian's back in May and she also just finished the drama Finding t.A.T.u. Barton is still hard at work on the high school comedy Assassination of a High School President with Bruce Willis. Walled In is a French-Canadian co-production and is scheduled to start shooting on October 22nd, in the most glamorous of all Canadian locations: Saskatchewan (believe me, it's funnier if you are a Canadian).
