With all the casting rumors , Fool contributor Tim Beyers says it's likely that Time Warner (NYSE:TWX.DL) and DC Entertainment are under way with plans to bring a Justice League movie to theaters by 2016.

The latest rumblings have either Dwayne Johnson or Denzel Washington in line to play the Green Lantern John Stewart, and Josh Holloway up for Aquaman. All potentially solid choices, Tim says.

But the bigger news may be that we're hearing anything at all. DC and Warner have their hands full with Arrow, which returned from midseason hiatus this week, a pilot for The Flash TV series starring Grant Gustin, and 2015's Batman vs. Superman. Gal Gadot will star as Wonder Woman in that film, joining Ben Affleck's Batman and Henry Cavill's Superman. With so much going on already, it's hard to imagine adding more characters to the mix -- unless the plan is to shoot Justice League right after Batman vs. Superman, building momentum for the DC Cinematic Universe.

Tim says that's likely, and preparing for it now is smart business. Marvel signed most of its stars to multipicture deals just as it was building out the universe. In one extreme case, the comic book king agreed to a nine-picture deal with Samuel L. Jackson to play S.H.I.E.L.D. boss Nick Fury. DC may be taking the same approach by courting Johnson, Washington, and Holloway now, before an official Justice League film is in the works.
