This affectionate fan tribute to the legendary stop-motion special effects artist is distinguished by the fact that the fans paying tribute are among the most successful directors in the world.
Siobhan Synnot, Scotsman
A little too exhaustive in its detail, but if you loved his febrile creations in Jason And The Argonauts or the Sinbad movies, it's worth catching.
Henry Northmore, The List
Essential viewing for any fantasy film fans.
Philip French, Observer [UK]
A continual delight.
Dave Golder, SFX Magazine
While a little light and fluffy - and not offering much insight or info that hasn't been covered in the numerous books on Harryhausen - it's a wonderful celebration of his work.
Andrew Pulver, Guardian [UK]
Harryhausen emerges as a charming, likable pioneer, a mood helped along by the adoring nature of this profile.
Antonia Quirke, Financial Times
The most fascinating point made in the film is that it was Harryhausen who invented the way we all think dinosaurs moved. Those gestures - adopted as truth even by palaeontologists - first came from him.
Robbie Collin, Daily Telegraph
A shallow, fannish tribute to the stop-motion master who made The 7th Voyage of Sinbad.
Adam Lee Davies, Little White Lies
You come away feeling Harryhausen perhaps deserves a more dynamic tribute, but it's a solid round-up of an extraordinary career.
Ian Freer, Empire Magazine
A fascinating and loving look at one of cinema's true greats.
Simon Kinnear, Total Film
Told with affection and unprecedented access, this is the definitive word on the career of one of cinema's most authentic geniuses.
