So this is where we are...complaining about what we weren't told at SDCC. Nevermind that SDCC is not the official release point for comic book movie info. Yes, last year riding on the box office success of [Man of Steel](movie:15593)'s initial release WB and Zack Snyder teased the theme of what we now know to be Batman v Superman: Dawn of Justice. However it was in the months between that Ben Affleck, Gal Gadot and Jesse Eisenberg's casting was revealed. The first image of Affleck as Batman was released a few months ago and now they have released the first image of Wonder Woman. All within reasonable amounts of time considering the movie is still twenty two months away from release. Thats another Comic-Con and two Super Bowls!
Man of Steel was shot in 2011 and not released until 2013, the first image of Henry Cavill as Supeman/Kal El was released some time in 2011 and left fans wondering whether we would be seeing shorts over tights (we didn't) but it was accepted and fans waited patiently for the first trailer which debuted not with The Hobbit in December of 2012 but the SuperBowl of 2013. At this rate we will get another "peek" at "[Batman v. Superman: Dawn of Justice](movie:711870)" next year at Comic-Con 2015, but won't see a full trailer until the Super Bowl in Febraury 2016. Sure there will be a few pics and all, but why would they release footage so soon?
"World War Z" and "[Mad Max: Fury Road](movie:41445)" are other examples of films with long times between principle photography and theatrical release. I say: let the filmmakers take their time and not worry about pleasing the fans at every stage. I don't need to know what the release date is for Justice League this far ahead. Nor do I need to know whether Dwayne Johnson is playing Captain Marvel or Black Adam until the movie is actually in production and even then, let the creative process take its due course not the marketing campaign. We have been spoiled on news sites and blogs teasing wild rumors and rushing to be "first" with an exclusive to the point where we are not even enjoying the news and info we are given. I hope we don't see a frame of Avengers: Age of Ultron until the Super Bowl 2015, but I also know we will find out what Marvel is doing after Captain America 3 releases way before then.
As for the reaction to what was actually revealed. I will say that Gal Gadot as [Wonder Woman](movie:45787) was not an unexpected take on the character. WB actually showed more of her uniform than when Bale, Affleck and Cavill were promo'd for their respective initial outings. Superhero uniforms in movies invariably progress from film to film. If Diana looks this way initially it makes sense that in their second outing (third film of the DCCU) she will have an updated version and by the time we see a solo film, I'm sure she will again be revamped. It's a real nice to be in a time where there is such instant feedback on relevant news to this genre and we are all anxious to see the next films, but we will soon be at a time of 4 or 5 superhero themed major releases a year. How much information can we be expected to digest if they are also touting films 3 and 4 years away? and I didn't even get into the TV shows.
