What happens when Earth's Mightiest Heroes (and Ultron) are reimagined as characters from The Wizard of Oz? Something pretty f**king weird to be honest. That makes this cleverly put together mashup trailer no less brilliant however, and while seeing the Cowardly Lion as Thor and the Scarecrow as Captain America is pretty nuts, Ultron as the Tin Man will ensure you never view the classic 1939 movie in the same way...anyway, share your thoughts on the video in the usual place!
