While discussions for a Dark Knight sequel continue, a new name has been tossed in the ring.
Justin Long -- who is already onboard as Ant-Man in the Marvel Comics movie -- is being considered to "fill in the story gaps" as the Joker in the next Batman installment.
While no deal has been set, a source on the WB lot confirms, "if the script goes that way, Justin is the only actor on the table. He's an exact fit."
On a hot streak since Live Free or Die Hard, 30 year-old Long is currently starring in He's Just Not That Into You, with Jen Aniston and Ben Affleck.
