Look, we've seen deepfakes of Danny DeVito and Dwayne Johsnon spliced together, we saw a deepfake that put Freddie Mercury into an episode of 'Mr. Robot', and there was even one of Jim Carrey being morphed into 'The Shining'.

You would think at this stage of the game - the game being the terrifying real-world implications of deepfake technology - that there's very little that will catch us off-guard with it. Yet, here we are, talking about a strange video that plants Robert Downey Jr., Tom Holland, Chrises Hemsworth and Pratt, into the world of Oz.

Tom Holland, it must be said, does look freakishly well-matched as Dorothy, right down to the pigtails, while putting Stan Lee in the place of Frank Morgan was a nice touch. Oddly enough, even without the whole Professor Marvel thing, there's another connection between Marvel and the Wizard of Oz.

The ill-fated prequel movie, 'Oz, The Great & Powerful', with James Franco in the lead role, was originally supposed to star Robert Downey Jr. before he bailed out for - you guessed it - the Marvel Cinematic Universe.

Anyway, here's the video.
