"The casting of Depp and Bale only hangs their lack of acting chops out in public for all to see.
Just because Mann cast them in his movie, it doesn't suddenly make them any good.
I wouldn't accuse them of acting badly based on what has gone before without giving them a chance and if you are going to redeem recent past work the best place to do it is in a Mann movie.
I'm looking forward to Mann's next project because I am more encouraged after Dillinger than after Miami Vice.
Maybe more success at the box office will allow him to regain control in casting too.
The correlation between being good looking and being a below par actor is a contemporary disease."
