A trailer for the Locke & Key pilot (based on the IDW comic series) that Fox decided not to air (see “Fox Passes on Locke & Key”) has turned up, although there’s little indication that the show itself is any closer to airing. Writer Josh Friedman Tweeted that “Nobody should make anything of its presence on the net” and indicated that it had been made while the pilot was still being produced.
The full pilot did screen at Comic-Con (see “Locke & Key Pilot to Screen at San Diego Comic-Con”).
