For instance, let?s say Sylvester Stallone ? star of this 2013 commercial about super-pens ? casually reminded people that for years he?s been trying to make a movie in which John Rambo, the Vietnam vet-turned-rogue avenger he?s been playing on-and-off since 1982?s First Blood, fought a monster. The actor and filmmaker created it, presumably in the wake of his post-Creed resurgence, to produce projects, including Samaritan, his ?dark, fresh take on the superhero genre,? which is to star Stallone himself.
