Yeah I watched both of those. Science of sleep looks good, and Bernal was terrific in motorcycle diaries so there's no reason to think he won't be good in this one, added to the fact it's from the people who brought us the delightful eternal sunshine.
As for the second one, yeah it does look cool, but I still don't quite understand the premise. How in the world could every woman all of a sudden lose the ability to reproduce!? They say pollution and genetic manipulation as possible reasons in the trailer, but both of those don't seem possible. For the pollution one, there must be areas of the world that are less polluted, and hence not as toxic, and for the genetic manipulation one, how would that make every living female incapable of reproduction (okay maybe if they created an airborne contagious RNAi virus that knocked down a gene required for pregnancy, but you'd think that some or alot of people would not be infected). However, barring the ridiculousness of the premise, it does seem like a cool scenario.
But when I read the title to this thread, I thought it was going to be a discussion of what the best movie trailers were. I vote for Garden State
