Rhett Reese and Paul Wernick, who penned the first two Deadpool films, will write the third movie based on the X-Men comic book character, created by Rob Liefeld. Lizzie Molyneux-Loeglin and Wendy Molyneux, Emmy-winning writers of Bobs Burgers, had been previously tapped to write Deadpool 3, but Reese and Wernick will instead return for a third outing.
Besides Reynolds, no other cast members are confirmed for Deadpool 3. The second Deadpool film introduced Josh Brolin as Cable and Zazie Beetz as Domino. Deadpool also starred Morena Baccarin as Vanessa and T.J. Miller as Weasel. Tim Miller directed the original movie, while David Leitch helmed Deadpool 2.
