It's not the first franchise picture McG has been attached to that almost changed the entire mythology of a beloved property. In the early aughts, McG was attached to "Flyby," a rebooting of the "Superman" series that, thanks to a boldly different take from screenwriter J.J. Abrams, would have made wholesale changes to the origins of Superman, his home planet Krypton, and his main nemesis Lex Luthor. McG ended up exiting the project when the studio was adamant about shooting in Australia. He blames his fear of flying for being "thrown off" that project, calling it his "rock-bottom" moment, which would eventually lead him to taking on his next film, the plane-crash drama "We Are Marshall," as a catharsis.
McG says no final casting decisions had been made on the film, though he did mention one name that, we admit, we hadn't heard before. "We had Robert Downey Jr. locked up to be Lex Luthor, which I think would have been extraordinary," McG enthused. But his pick for the Big Blue Boyscout is actually much less of a surprise. "Ironically, we liked Henry Cavill a lot, but we hadnt cast him yet," he says of the actor currently wearing the tights in the upcoming "Man Of Steel." "J.J. wrote the script, and we got that to a really good place in the end," he says of the film, the first in a proposed trilogy. "But Im to blame for [the film not happening]." While we've heard no shortage of superhero movie casting over the years, the idea of a then-low-key Downey Jr. as Lex Luthor is enough to make us wonder a whole score of what-if fantasies, particularly considering his own subsequent ascension to the top of the A-List following "Iron Man."
