If you force-fed horse tranquilizers to "The Bourne Identity," you'd end up with something like "Limits of Control."
It's a postured anti-thriller from Jim Jarmusch, king of the deadpan art film. Jarmusch regular Isaach De Bankole stars as a courier/spy (the anti-thriller gag would have been funnier with Jason Statham) who's hopping about Spain delivering diamonds and other unspecified things to a series of colorful contacts.
It's a scenario that allows Jarmusch to play around with a hip cast of stars (Tilda Swinton, Gael Garcia Bernal, Bill Murray, Youki Kudoh, Hiam Abbass). This will no doubt help Jarmusch with overseas sales, but it doesn't help the viewer come any closer to figuring out why they should be watching.
