Joss Whedon has opened up about the superhero movies trend and spoke in length about the exciting rivalry between Marvel and DC films. According to the Avengers director, Marvel is more successful systematically, whereas DC is more cinematic.

Whedon told Complex.com, "I did not see Suicide Squad. I saw Batman vs. Superman. Everybody's got their own method. I think Marvel has been more successful systematically. DC has been more cinematic — their stuff looks amazing — but I feel like Kevin [Feige, President of Marvel Studios] is a really good storyteller. He really cares about coherence, and I feel like style never defeats substance at Marvel, but a little style creeps in."

Speaking about Marvel and DC TV shows, the filmmaker explained, "Ant-Man had some, Doctor Strange might be funky, and they are doing very fun things on TV. The Marvel-Netflix thing is working really well. DC's decision to have their shows on TV with different actors playing the same characters at the same time as their movies, is a little interesting."

The Buffy The Vampire Slayer creator also revealed that he watched the new Wonder Woman movie trailer and described it as "wonderful."

Whedon said, "I want it to be good. The trailer was just wonderful. I'll probably be disappointed, me more than anybody else, because I'll be like, "Wow, my version..." or whatever, but I can still get myself up for it. The trailer had her shield and her fire hammer and yep, I'm good, this will be fine, everything is good. Such an image."

Marvel's Doctor Strange is set for release on 25 October in the UK and 5 November in the US. While DC's Wonder Woman will hit theatres on 2 June 2017.
