Parallels was created as a television pilot, but Fox Digital Studios morphed it into a stand-alone movie.

North Korea's Ryugyong Hotel is pasted into the skyline of the futuristic version of the city (at around 45 mins).

In the 'Happy Death Days' films, Jessica Rothe also plays a character who travels to alternate universes/realities.

The front door of alternate Harry's apartment building is really just another side of the same building, located at 1010 Common St, New Orleans.
