The Guardians of the Galaxy director, who is currently working on a new Superman movie, made the comment on Threads when a user criticised superhero movies for featuring cameos for no substantial narrative reason. "I call that 'Cameo Porn' and it has been one of the worst elements of recent superhero films. If a character is in film, they have to have a reason to be there story-wise.". The Suicide Squad filmmaker clarified that he is not opposed to cameos in general, but he does not approve of character appearances that distract from, or add nothing to, the story.
