The Justice League will be making their first big-screen appearance in Batman v. Superman, but we almost had a film featuring the team in 2009. Locations were scouted, production art was done, and casting was completed, but the writers’ strike in 2007 sidelined the project just long enough for Nolan’s Dark Knight trilogy to send Warner Bros. in a different direction. Could the director of Happy Feet have pulled it off? We’ll never know.
