The books were so badly written I think that's the only reason I'll go see the film, I'm just intrigued how they'll do it without making it porn
I don't think they'll have trouble adapting it to film, even if they keep in the BDSM; the book wasn't really that racy to begin with.
I think the guy they chose is sexy although not who I had pictured while reading the books (for some reason I always pictured David Beckham?). I actually saw the first episode of Arrow right after I finished the books and was immediately like, "THAT guy should be Christian Grey!"
Alexander Skarsgard would've been good in theory but he can't pass for 27.
