Parallels is a 2015 American science-fiction adventure film, originally conceived as a television pilot, derived from a story by Christopher Leone and Laura Harkcom.

[1] Mark Hapka, Jessica Rothe, Eric Jungmann, and Constance Wu star as people who are thrown into alternate Earths that range from subtly different to post-apocalyptic.

[3] It was announced on November 16, 2016 that Neil Gaiman would be collaborating with Christopher Leone and Albert Kim to adapt the teaser/trailer film into a TV series, titled "The Building".

Initially dismissive of the seemingly nonsensical graffiti, they discover that the building has transported them to an alternate Earth devastated by nuclear blasts.

Stone, suddenly distrustful of outsiders who know both his name and former occupation, takes them hostage and orders Tinker, the local surgeon and gadget-man, to interrogate them.

Harry sends evidence of his double's wrongdoing to the media, and they return to the building, where they find that Tinker has apparently taken Ronan and Polly hostage.

Alex leaves the building after telling Ronan and Beatrix that they must find their mother, who they insist is dead, in order to return to the core world.

After the building transports them once again, three different versions of Polly convene in secret and two of them play rock-paper-scissors to presumably determine who will accompany the rest of the group into the next world.
