A botched burglary left the safecracking Patrick "Eel" O'Brian shot and exposed to a mysterious chemical that gave him superhuman elasticity, shapeshifting and invulnerability. His powers would later lead to Batman recruiting him for the Justice League.
If Ben Affleck's Batman ever goes on another recruitment spree for the Justice League, would you like to see Plastic Man among one of the candidates? If so, actor Ben Schwartz is definitely throwing his hat into the ring to play the character. Best known for Parks and Recreation and House of Lies, Schwartz also has an extensive career as a voice actor, with roles in the Duck Tales reboot, Bojack Horseman, and Bob's Burgers.
Not much is known about the overall direction the DCEU is heading but WB could do far worse than the likes of Plastic Man.
