According to Comics Continuum, DC Entertainment has handed the directing reins of the upcoming animated film to Sam Liu, who also directed Jutice League Crisis on Two Earths and Superman/Batman Public Enemies. Liu also directed the two Hulk VS animated films for Marvel Animation:
"An announcement is expected soon on the voice of Green Arrow in the DC Showcase short that will accompany a DC Universe animated movie release.
The Green Arrow short was written by Greg Weisman, who is producing the Young Justice series for Cartoon Network.
"It's a pretty lively piece," producer Alan Burnett said."
Warner Bros. has yet to confirm the film's existence as it is not on their official release schedule.
