As television panels gear up at Comic-Con 2012 this week, we've got a look at exclusive posters from some of your favorite shows from Warner Bros. and more! Are you ready to stare into the dreamy eyes of the Winchester brothers of 'Supernatural'? We don't think so, but go ahead.

The images below come courtesy of THR (Warner Bros. images) and CinemaBlend ('Spartacus'), and while they don't give us any indication of where the latest seasons of the returning shows are heading, they're at least pretty, no?

'Supernatural' is moving into its eighth season, premiering on October 3, with the season 7 DVD and Blu-ray set to release on September 18 -- that gives you plenty of time to catch up or revisit the last season before the season 8 premiere.

There's also posters for the new CW series 'Arrow,' based on the comic book character Green Arrow, and the new Fox series 'The Following,' starring Kevin Bacon -- which means everyone on Fox is now one degree away from Kevin Bacon in the Kevin Bacon game. Bacon.

'The Big Bang Theory' (we know, we don't like it either) returns for its sixth season on September 27 on CBS. For a complete 180, there's 'Spartacus: War of the Damned,' which heads to Starz and promises the "end begins" in January, 2013.

New series '666 Park Avenue' stars 'Lost' alum Terry O'Quinn as the owner of a spooky building that a new young couple agree to manage. Also, Vanessa Williams? The poster doesn't include a premiere date, but it assures you that you can find the show on ABC every Sunday night.

And finally, CW's 'The Vampire Diaries' returns for season 4 on October 11, and 'Nikita' enters its third season on October 19.
