Marvel Studios’ long-gestating Phase Three feature Black Panther, which recently signed Joe Robert Cole for scripting duties and saw its release date moved up from July 2018 to February of that year, so far has had a mighty difficult time locking down the perfect director.

Ava DuVernay (Selma) was first offered the gig over the summer, but she took a pass, as did F. Gary Gray (Straight Outta Compton), who signed on to direct Furious 8 for Universal instead. Marvel seems determined to secure the services of a first-rate filmmaker, and according to a new rumor it appears that they may have found a new front-runner in Ryan Coogler.

It was almost a banner year for Colin Trevorrow. Following his Sundance film festival hit Safety Not Guaranteed, he came out with his second major directorial effort, this summer’s Jurassic World. The fourth film of the franchise beat Marvel’s The Avengers‘s record for the number one weekend opening film at the worldwide box office. He was then recently named as director of Star Wars: Episode IX.

But now, the director finds himself in a bit of hot water after he attempted to address the issue of gender inequality in Hollywood. This has been an on-going issue, with many fighting for gender and racial diversity on the creative and performance front. In an attempt to explain this problem, Trevorrow has found himself on the receiving end of much criticism. After the jump see what he had to say, and how some are responding to his Twitter post.

Ava DuVernay‘s stunning work on Selma put her as one of the frontrunners to direct Black Panther. Though there was some initial excitement on the possibility, DuVernay ultimately walked away from the job, citing creative differences as the reason. “Marvel has a certain way of doing things and I think they’re fantastic and a lot of people love what they do. I loved that they reached out to me,” said DuVernay.

As we have all seen before with Patty Jenkins, Edgar Wright, Alan Taylor, and Joss Whedon, all had to work under the Marvel guidelines, connecting their work to the collective Marvel Cinematic Universe. Not really an easy job when you want to maintain your creative input, while being pressured to be part of a universe you may not be as concerned with.

As Phase 2 of the Marvel Cinematic Universe comes to a close with Ant-Man, Marvel Studios is looking to the future by continuing to develop their future projects. With Captain America: Civil War currently shooting, and Guardians of the Galaxy Vol. 2 set to shoot later next year, films like Thor: Ragnarok, Captain Marvel, and Black Panther are going to be on the lookout for possible directors. Now Ava DuVernay, the director of the Academy Award nominated Selma, who was rumored to direct Black Panther, is now taking herself out of the running.

Despite some behind-the-scenes tensions — Edgar Wright and Patty Jenkins immediately come to mind, while Joss Whedon isn’t shy about some of the troubles he has had — Marvel manages to find the right person to direct their films. Now, the studio is setting their sights on the director of the Oscar-nominated Selma. According to a report from The Wrap, Selma director Ava DuVernay is being courted to direct a Marvel film. We just don’t know which one yet. For more on this story below.
