Played in cities across the country, the sixth feature-length special was also celebrated in a VIP premiere at the Vue's Leciester Square.
The event held on September 1st saw recognisable figures in Britain attend the celebratory screening.
Perhaps the most famous person to join the party was Olympic champion, Mo Farah. The Somalian athlete, who brought his daughter Rihanna to see the film, posed for a photo with The Fat Controller, both doing his Mobot symbol.
Another known figure was television personality and ex-wife of The Rolling Stones' Ronnie Wood, Jo Wood. The former model was aided by her grandchildren to the prestigious show.
Others who turned out for the fun included cricketer James Anderson, Eastenders' Jo Joyner, model Danielle O' Hara, presenter Kate Garraway and Iranian-born British comedienne Shappi Khorsandi.
More so were singer Stacey Solomon, actor Shaun Dooley, comedienne Katherine Ryan and milkshake! presenters Olivia Birchenough and Kemi Majeks.
Thomas & Friends UK's Twitter were on hand promote the special day and to thank the attendees.
