First I have to confess Alfred Hitchcock is not my favorite filmmaker - perhaps partly due to the somewhat clunky exposition he sometimes used but there are elements of Anthony Zimmer which I enjoyed and which recalled Hitchcock at his best. As so many have said before me Sophie Marceau is very,very good in Anthony Zimmer but , for me, Yvan Attal was the standout. I have liked his somewhat deadpan style since "Les Patriots" (still one of my favorite thrillers) and here, as the 'ordinary' guy supposedly caught up in things beyond his knowledge he plays a much more realistic Cary Grant type than you would usually see in a Hitchcock movie. Sure, you can tell pretty quickly he's not really who he seems to be but then how long did it take you to figure that Grant wasn't all he seemed in "North By Northwest". That's part of the fun of films like Anthony Zimmer. I've seen "Zimmer" twice and I'll be more than happy to watch it again.
