'Castle' turns up the heat with sexy Season 5 cast pictures!
The moody, atmospheric setting takes us back to "The Blue Butterfly" noir episode -- and Castle ( Nathan Fillion) and Beckett's ( Stana Katic) very first kiss. That was imaginary, but we're pretty sure we can count on some real smooching this season.
Check out our photo gallery of the pretty cast and tell us what you think.
"Castle" returns Monday, Sept. 24 on ABC.
