The Suicide Squad director James Gunn has explained why Sylvester Stallone’s King Shark’s design in the movie is slightly different than his look from the source material. Writing on Twitter, Gunn confirmed that he did in fact conduct tests with King Shark’s original hammerhead design, and he thought he might end up using it. However, the fact that the shark’s eyes are so far apart made for some “incredibly awkward shooting interactions” with other characters.
“I did tests with the hammerhead design, which I love & originally thought I’d use,” he said. “But having eyes on the sides far apart made it incredibly awkward shooting interactions with other people. You couldn’t really see him looking at the other person & the shots tended to be too wide.”
