'The Man Who Took Thomas To CGI'

Greg Tiernan has worked on numerous feature films and TV Series both live action and animated, before launching Nitrogen Studios with wife and business partner, Nicole Stinn, in 2003.  


Both had read the Railway Series books in their youth, and were familiar with the world of Thomas the Tank Engine and his friends on the Island of Sodor prior to being approached by HIT Entertainment in 2007 when HIT Entertainment were toying with the idea of switching the methods of production from live action models to CGI animation.

Although initially the switchover was met with a deal of anxiety and animosity, Greg and his team have worked tirelessly to make sure that everyone can see the benefits of what a full CGI Sodor has to offer.  And, with a passion for the original Railway Series stories and the Rev Awdry’s original characters, he’s been both a natural and wonderful choice to lead the series into this brand new production medium.


Since the switchover, Thomas’s DVD sales and viewing figures have soared across the world as fans embrace the wonders that Nitrogen Studios can provide in visual quality.  It has opened up new doors for Thomas and Friends, and for Nitrogen Studios.

In 2009, Greg met and befriended members of the SiF Staff team at the Hero of the Rails premiere in London, and since then has kept up a regular and friendly correspondence with us.  In 2011, he surprised us all when he sunk £500 into the E-bay auction we were running to raise funds for Clic Sargent Children’s Cancer Charity.  Greg won the auction and kindly handed the books on offer to the second highest bidder.


Greg and his Nitrogen Studios team strived to maintain the visual standards set by David Mitton, Steve Asquith and Britt Allcroft - and occasionally, they could be seen to exceed them!  Sadly, Nitrogen lost the contract for Thomas's production in 2012.  However, Greg and Nitrogen went on to become the Animators for the adult CGI film, Sausage Party and he has been involved with the new CGI Addams Family movie too!


Greg talks about his work on Thomas & Friends and the other famous animated features he's worked on over the years!
