I'm really flabbergasted most going on about Russian accent. I have relatives from there and was surprised how well Jennifer actually did one. Jeremy Irons not so much as i realized it was him because his english accent came out. Movie had a cold feel but it was actually decent. Jennifer even looked Russian so I credit to that as well. Mathias is good in everything I've seen him in. He's Belgium but play Americans well and was very good in this. He's a very diverse actor. I guess I liked the film enough to come here and read what others thought and write a review. Out of the last 10 or so movies I watched I thought this was pretty decent .
