->The thing with ''Leap Year'' is this - we saw it yesterday, although I actually really saw it several weeks ago when I saw the trailer. [...] And I made a note of it, that took us up to one hour and 17 minutes into the movie, which clocks in at just over 90. So the trailer left 12 minutes of the movie unknown. Blimey, I didn't expect the nuclear strike that happens in that last 12 minutes.
