The Upside Down Movie

The Upside Down Movie is an cancelled special episode that was fully scripted by David Collins and Shane Dundas from 2008 to 2010. It was planned to act as the proper series finale of The Upside Down Show.

The movie was first announced by the newspaper The Australian in August 2008. In November 2008, David Collins announced in an interview with the Sydney Morning Herald that the movie was planned to start filming in 2009.

Nickelodeon Australia funded the script development, but the crew needed financial support from outside investors to start filming, which never happened in 2009. Collins started an online petition in 2010 to show public interest in the movie, but it never gained enough support and the project has been in limbo ever since.

Plot
Very little information about the movie's storyline was revealed. However, it is known that the movie was actually planned not to follow the show's basic episode structure. In September 2008, in response to questions about the plot, the moderator of the Umbilical Brothers' website said:
