We know this story is old but I do not think it got enough press, not to mention it came out on the heels of the San Diego Comic-Con. With CBS’ Supergirl coming out in October, the biggest question was whether her cousin that is overly mentioned in the trailer for the pilot will make an appearance in the series, at all.
Many should remember that the creators of Arrow said that certain characters were off limits to television like Batman and Superman, which means shows like The Flash and Arrow had to stay away from those franchise characters. Warner Bros. has stated that their TV universe will be vastly different from the movie universe, as we are seeing with the Suicide Squad movie.
The question was given to the producers if we would ever see Superman in the new series. The short answer: no.
“Our prototype is the way the president is seen on Veep,” executive producer Ali Adler tells EW, referring to the HBO drama’s clever way of mentioning, but never showing POTUS. “It’s certainly [inspired by] so much of what Julia-Louis Dreyfus’ character goes through. Ultimately, this is a show about Supergirl and we really want to see it through her lens.”
Even though he makes a very backlit appearance in the pilot, we know that he is not Henry Cavill. We can say that it sort of bums people out but it is not surprising. The major issue, story-wise, if that once you introduce Superman or Batman, the episode will quickly be about them. We will have to see who else will be thrown in there instead.
