'last night' is a universal slice of life story. i can only imagine we have all had a 'last night'. i certainly have. a couple is separated for 24 hours, in this case because of a business trip, and events just unfold. the events being people. one a business associate: the other a former lover. temptation and old feelings surface. different decisions are made. the overriding consequences not immediately known.
keira knightley shines. sam worthington and guillaume canet are more than effective in their respective roles. the only weak link is eva mendes. really, would anyone cheat on keira with eva? it's like beauty vs a second hand rose. a better looking actress, or at the very least a better actress, would have made a temptation more plausible. but as we all know most men do not think with their heads but rather think from below our waists. that's a fact!
this one bit of miscasting does not diminish the whole however. this is definitely worth a viewing or two. you may relate. i sure did.
