15 Failed Comic Book TV Shows That Only Lasted One Episode

2. Locke & Key (2011)

Locke & Key is a modern haunted house story (in comics written by Joe Hill and drawn by Gabriel Rodriguez) about a new widow and her three children who move into the late father's sprawling family estate, which has a series of keys with special powers, a malevolent spirit and lots of other creepy things going on.

The subsequent pilot episode for a proposed series was produced by Fox but never actually picked up for a full season. Though, that didn't stop the show's creators from taking it to Comic-Con in 2011, which was a bit unusual. Here was a screening for a pilot that hadn't been picked up by its network, that was never going to air anywhere, and that comics publisher IDW had gotten special permission to show just because they wanted fans of the Locke & Key comic to get a chance to see the work.

However, all hope is not lost for fans of the comic series. Earlier this year, Joe Hill announced that Universal Studios had signed on to adapt Locke & Key into a trilogy of films. No other specifics were given but you still have permission to get a little excited if you so choose to.
