Relativity Media has released the trailer and poster for Limitless (previously titled "The Dark Fields").  The film centers on a struggling writer (Bradley Cooper) who takes a special drug that allows him to utilize his entire mental capacity.  Setting aside the fact that your brain doesn't work on capacity but instead handles various functions, the film looks like it could be an interesting thriller...or a complete garbage.  While I liked Cooper back when he was on Alias, I don't know if he can carry film.  Also, I'm not crazy about rooting for a protagonist whose "perfect" life is simply being disgustingly rich.  Hopefully director Neil Burger (The Illusionist) can pull it all together, although this is his first feature where he didn't also write the screenplay. The script was penned by Leslie Dixon (Pay It Forward) based on the book by Alan Glynn.

Hit the jump to check out the trailer and poster.  Limitless also stars Abbie Cornish, Anna Friel, and Robert De Niro.  It opens March 18, 2011.  Click here to check out the viral promo ad for the film.

Bradley Cooper and Robert De Niro star in Limitless, a paranoia-fueled action thriller about an unpublished writer whose life is transformed by a top-secret smart drug that allows him to use 100% of his brain and become a perfect version of himself. His enhanced abilities soon attract shadowy forces that threaten his new life in this darkly comic and provocative film.
