I have watched this film so many times on so many different formats; watched it on the big screen, small screen, iTunes Digital Download and even hearing it Live In Concert with the Philharmonic Orchestra playing the score at Cadogan Hall! The film is a modern classic to the TV series in its own right. It pays tribute to it's roots as it was to celebrate the 70th Anniversary of the Railway Series, using lots of Awdry-related material whilst keeping the plot solid and moving along well. Elements of comedy, action, betrayal etc. help to drive Thomas & Friends into a situation they've never been through before.
With the voice talents of Olivia Colman (Marion), Sir John Hurt (Sailor John), Eddie Redmayne (Ryan) and John Hasler as Thomas the Tank Engine, it brings the cleverly-written dialogue to life which will entertain all the family. Give it a watch! 9/10
P.s - the 1080p download is heaven when it comes to Arc Production's CG animation. Also, be on the look out for a CG reincarnation of the Thin Clergyman himself!
