I don't think we're in Kansas anymore, Falcon. Darren Wallace is an Australian special effects artist who gets his kicks mashing up disparate films into uncanny parody trailers. His latest such clip may be his greatest masterwork yet.
When you think about it, Ultron in "Avengers: Age of Ultron" is really just the Tin Man from "Wizard of Oz," except without a moral compass. He's a heartless mechanical creation who joins up with other unfortunate downtrodden souls to reach his own end. Okay, so that's stretching the Tin Man's motives some, but stick with it for a minute and you'll enjoy the heck out of Wallace's "Avengers of Oz: Age of Tin Man" trailer.
Wallace recast The Scarecrow as Captain America (presumably post-brain implant), Dorothy as Black Widow (Toto's in there too!), and The Lion as Thor (mainly because of the hair, not the courage). Quicksilver and Scarlet Witch get their Oz makeovers as well. Check it out below.
