Come On It would be the most bizarre / unexpected / awesome thing ever.
Seriously De Niro, Streep and Duvall need to be in a Marvel or DC And I vote for DC.
This who I think you DC should hire.
I would be very happy if any of my wishes would come true. But none of them will probably do it.
Although Seth MacFarlane would be super fun as a comic Batman villain.
