The Magic Roundabout 2

The Magic Roundabout 2 (also known in the US as Doogal 2) is a cancelled sequel to the 2005 French-British computer-animated adventure fantasy film The Magic Roundabout (known in the US as the infamous Doogal), which is based on the television series of the same name. Action Synthese, the company that produced the first film was already developing the sequel since 2004, but it was quietly cancelled 9 years later due to the closure of said company in 2013 before the sequel and a animated film based on The Wonderful Wizard of Oz could be completed, as well as the American dub's critical and commercial failure.

Why It Was Cancelled

 * 1) Plans for a sequel to The Magic Roundabout (Doogal) were cancelled due to the closure of Action Synthese in 2013, before the sequel, along with an animated film based on the popular novel The Wonderful Wizard of Oz could be completed (mentioned earlier).
 * 2) Although the original French-British version was a critical and commercial success, the American version (Doogal) of the first film was widly panned by critics, audiences and fans of the original show alike, and was also a box office failure (mentioned earlier).
 * 3) Daniel Tay and Lee Evans both retired from acting in 2009 and 2014 respectively, and could not reprise their roles as Doogal (in the American version) and the Train (in the UK version) respectively.
 * 4) Henri Salvador and Michel Galabru expressed no interest in returning as Doogal and Zeebad in the French version before they died in 2008 and 2016 respectively.
 * 5) The cast and crew of the first film moved on to other projects, while some had retired and/or died.

Results

 * The sequel was permanently cancelled.
 * The sequel, along with the animated film adaptation of The Wonderful Wizard of Oz were also shelved and will probably remain so for eternity. No video footage or screenshots of the two films have ever been released, so they are most likely lost as well.
 * From 2008 to 2010, Action Synthese released a CGI animated reboot of The Magic Roundabout series, which served as a follow up to the film of the same name, as well as the finale to The Magic Roundabout franchise.
 * The Magic Roundabout (Doogal) film is a stand alone film, and is also the only completed film from Action Synthese before the company's closure in 2013.
