“Two engines are much better than one, you know.”

Big World! Big Adventures! is the 2018 Thomas & Friends film.



Big World! Big Adventures!, alongside the twenty-second series, mark the third major reboot of the franchise, following the introduction of the Steam Team in the eighth series and the show switching over to full CGI in Hero of the Rails. Both productions were the result of the market research Mattel conducted with audiences around the globe. It was about how Mattel could keep Thomas & Friends relevant in a competitive market, as well as reversing declining toy sales. The one suggestion Mattel was intrigued with came from a child declaring that "Thomas is a train but he never really goes anywhere." This evolved into Thomas travelling around the globe and learning about different cultures.  


When a mischievous little racing car called Ace passes through Sodor on his way around the world, Thomas is inspired to embark on his own ambitious trip. Traveling full steam ahead across five continents, Thomas discovers magnificent new sights and experiences exciting places and cultures. Along the way, he makes friends with an inspiring and fun Kenyan engine called Nia. With so much for Thomas to learn about the world, will Nia be successful in teaching him a lesson about the true meaning of friendship? Featuring a world of wonder, curiosity and amazing animal friends, join Thomas on an epic adventure, fulfilling his dream of seeing the world!

  • According to The Fan Carpet, the film took twenty-one months to produce, nine months to animate and took over 9,500 hours of animation to complete. As such, this production took the longest time out of any Thomas & Friends production to date.


  • In both dubs, Joe Mills and Tracy-Ann Oberman are not credited for voicing Douglas, Oliver and Daisy.
  • When Ace jumps over the fence near Flying Scotsman, his front bumper clips through the rails as he lands. When he lands, his wheels stop moving.

    • In the overhead shot of Knapford Yards, Norman, Stanley and Stafford's eyes are not animated and appear closed.
    • Ben's body has been raised noticeably higher compared to his chassis so his buffers are touching the ones in the truck he was pushing.
  • After Nia says "I didn't mean to hurt your feelings," Thomas' train disappears before the scene changes. Thomas' very long train in this scene has a brake van at the end of the train, but for the rest of the time it is on screen, it is absent.
  • When Kwaku speaks to Thomas, the paint on Thomas' right tank is chipped.
  • In the wide shot of Guanabara Bay upon Thomas and Nia's arrival, the train pulled by the grey tender engine has a narrow gauge brakevan.
  • In the wide shot of Thomas looking at all the coffee trucks, a lamp in the background is floating.
  • Ace clips through a bush when he is racing in the Amazon.
  • Kobe tells Sir Topham Hatt that he loaded Thomas onto the ship to Brazil, when earlier in the special, the faceless grey crane near him was shown to actually be the one loading the engines.
