I do want to see this mainly because it looks interesting and it has both Saoirse Ronan & Gemma Arterton. Ronan is one of the best actresses working today and Arterton is one of the most beautiful actresses working today (she's one of my celeb crushes).
About Gemma, she is such a beautiful woman but still has yet to impress me with her acting same with Freida Pinto. She did show some flashes of her acting skills in the very underrated Disappearance Of Alice Creed but again, she needs to get it going. I don't know if it'll be this movie but she needs to break out of it soon. I have faith in her.
