Well, I don't know what the hell they're talking about in this "Explosive Extended Edition" DVD, since I selected said special edition to watch when the menu came up before the movie, and aside from poorly executed "bookend" scenes before and after the film proper, I didn't see anything new that qualified as remotely "explosive."
That aside, the theatrical version is an excellent spy thriller, combining amnesia, better-than-Bond spy action, and that Franka Potente chick from Run Lola Run. 5 stars.
