Dorothy Gale is swept away to a magical land in a tornado and embarks on a quest to see the Wizard who can help her return home.
It has been remastered and revived on giant Imax screens and in 3D: the best possible reason for taking another look at this extraordinary film, whose images can be savoured on a gasp-inducing scale.
Looks and sounds wonderful if historic cinematic gold is your thing.
Seventy-five years on, it hasn't dated in the slightest. Its use of colour, music and trompe-l'oeil effects still astounds, as does Judy Garland's extraordinarily febrile and emotional performance as Dorothy.
Just don’t forget your 3D ruby slippers if you want to get home.
Why impose stereoscopy on images that never felt the least bit flat in the first place?
