We're right smack in the middle of Upfronts week, and ABC just made a lot of TV fans very happy -- by releasing a gaggle of spankin' new trailers that feature many of our long-time favorites. An obvious standout is Nashville, a country music drama starring Friday Night Lights and American Horror Story alum Connie Britton as a fading country star who faces off against a young and nasty Hayden Panettiere.

But that's not all, y'all: ABC has also released the trailer for the highly anticipated Last Resort, an ambitious project created by Shawn Ryan of The Shield fame. Resort, a drama that follows the crew of a rogue nuclear submarine, features an all-star cast that includes Andre Braugher, Bruce Davison, The OC's Autumn Reeser and Felicity's Scott Speedman. (Team Ben forever!)

Check out these standouts and more below -- and be sure to look out for 666 Park Avenue, a supernatural freakout that stars Lost alum Terry O'Quinn and Vanessa Williams as a devilish married couple. A match made in TV heaven?
