Batman vs Superman Movie: 10 Cameos We Hope To See

10. Scarecrow

It's been a running joke throughout Christopher Nolan's Batman movies that Cillian Murphy's Scarecrow just won't go away: after being foiled by Bats in the first movie, he shows up again with his fear compound at the start of The Dark Knight, only to again be taken into custody by the Caped Crusader, and in The Dark Knight Rises, he again re-appears as the judge of Bane's ridiculous kangaroo court, quipping his much-quoted line, "Death...by exile." The Cameo: This one pretty much writes itself. How cool would it be to see Superman exposed to Scarecrow's fear toxin? What sort of ridiculous, awesome images could this conjure up? With a director as visually lavish as Snyder, the results could be fascinating. Granted, that would probably require more than a mere cameo to set-up, but failing that, perhaps a blink-and-you'll-miss-it appearance in one scene, making it clear once again that he's still kicking around and a viable threat for future movies.
