According to an interview with SiF, Greg Tiernan says he would like to remake Pop Goes the Diesel and Dirty Work. And, if it was his choice, he would reintroduce every character ever introduced.
Tiernan was involved in the animation of "Happily N'Ever After", the last film in which George Carlin played a part.
In an interview on 98.3 Vancouver, Tiernan told the hosts of the radio station the reason why they stopped working on Thomas, was due to the fact that they only wanted their team to focus on one project instead of doing multiple projects at the same time. But did enjoy working on the show while it lasted.
