The Adventures of Thomas

The Adventures of Thomas was a planned film starring Thomas the Tank Engine. It would have been made by HIT Entertainment along with CGI provided by Weta Digital.

Plot
The plot would have revolved around a boy who discovers the Island of Sodor, a place his father has visited before, but fails to remember. It is also confirmed that it would have a steam engines vs diesel engines conflict.

Why It Was Cancelled

 * 1) The last theatrical Thomas film, Thomas and the Magic Railroad was considered a failure.
 * 2) The plot of this movie is very similar to one of the side-plots in Thomas and the Magic Railroad.
 * 3) The steam vs diesels conflict has also been done before in the straight-to-DVD movie Calling All Engines!.
 * 4) It got stuck in the development vault for a long time, first it was set to be released in 2010, but then was changed to 2012, then to 2013, and then to 2014.
 * 5) Mattel took over HIT Entertainment (who was working on the movie) in 2013, meaning Mattel may have dropped production for this movie to make room for production of other projects such as Season 17 and more straight-to-dvd films.

Result

 * The film was permanently cancelled.
 * Trinity Entertainment Motion Pictures Studios and DreamWorks Pictures will release its first theatrical film based on Thomas the Tank Engine series, since Thomas and the Magic Railroad.

Trivia

 * This film would have been aimed for older Thomas fans than for generally younger Thomas fans.
 * Much like Thomas and the Magic Railroad, this film would have used live-action sequences, but would have a mix of CGI instead of electric model trains with static clay faces.
 * According to an interview with UCLA Magazine, this movie would have been released in 2013, it is however unknown if this is true or not.
