There's a very good reason why there's no Justice League movie on the horizon, while the Avengers are ready to take cinemas by storm:See, the Avengers have their wonderful, ready-for-marketing-and-reviewer-headline-puns catchphrase.
Whereas the Justice League has...umm...well...
(I'm certain that someone more knowledgeable of DC minutiae than I will chime in with some catch phrase the JLA has employed at various times. Two rules: if Snapper Carr said it, it counts as a negative. If the Detroit League said it, it's two demerits. Because, come on, a movie with the Detroit League??)
So, if we really want to get Warners off their ass on the Justice League movie, we need to come up with a snappy, zingy, brain-worm of a battle cry for them, that will make it even easier for them to sell toys.
"Justice League, Jostle!!"
Um, OK, this needs work...feel free to chime in here, guys...
And don't get me started on the fact that Marvel overall has better catch-phraseology than DC. Where's their equivalent of "It's Clobberin' Time!", I ask you? 'nuff said.
