The press around Deadpool 3 has focused heavily on the cameos, callbacks, and references packed into the hotly-anticipated sequel. Little is known about the film's narrative. The Merc' with a Mouth's first outing was a straightforward narrative with a traditional villain. His second film escaped that structure by pairing Wade Wilson with anti-hero Cable to stop a potential antagonist from becoming evil. Deadpool 3 will star Emma Corrin in a villainous role, and recent rumors suggest she'll play Cassandra Nova.
