Which raises the question of why DC/WB don't get some
of the people working on the animation to do the live-action
ones as well.
Also, Marvel can farm their characters out to several
studios: Spiderman (Columbia), X-Men (Fox),
Paramont (the various Avengers heroes). DC are
stuck with WB.
Not true, Marvel is owned by Disney, and the only reason Spider-Man and X-Men are still with those other companies is that they have to honour the existing contracts. Paramount's deal has been reneged and Avengers Assemble is actually being distributed by Disney, under Paramount's name, as compensation for Paramount's deal being prematurely ended.
