Before Jason Momoa got to tear into the DC Universe as Lobo, another fan-favorite actor came surprisingly close to playing the Main Man. Goldsman held the rights to Lobo at the time and approached Morgan about potentially taking on the character. The funny thing is, Morgan initially had no idea who Lobo even was, he said: “I had never heard of Lobo, and so I dove right in. We've seen the actor bring plenty of swagger, menace, and dark comedy to characters over the years, and Lobo would've given him the chance to crank all of those qualities up several notches. Jason Momoa is the Main Man now, but Jeffrey Dean Morgan as Lobo remains one hell of a fun DC casting "what if."
