Have they ever considered or asked Bruce Timm to get involved with live action DC movies?
Does Timm do live action? If so I would love to see this.
I think Warner Bros. has always maintained a "Let the cartoon people do their thing, and we'll do our thing" when it comes to live-action projects.
It's also pretty telling back when Batman and Robin was released, they delayed the direct-to-video animated Sub-Zero movie (which also had Mr. Freeze and Batgirl) several months because Sub-Zero was a better movie than B&R, and WB didn't want to be upstaged by an "inferior"
project. This is even more galling when you realize there was B&R merchandise released that has the movie characters done up in an animated style!
