James Gunn‘s last directorial effort in the MCU — Guardians of the Galaxy Vol. 3 — has come out and he’s now shifting gears to DC full-time as the co-head of the DCU with Peter Safran. As he heads into production on Superman: Legacy, the director addresses the never-ending rumors surrounding his future slate.

“I’m getting barraged with bulls**t DC rumors this morning,” said Gunn in a Tweet.

He continued, “I’ll just reiterate the general rule not to believe anything unless it comes from me or Peter [Safran]. But, unless it’s especially egregious, I’m going to slow down on calling s**t out (Sorry, I know it’s one of my favorite traditions). 1) Some people are making up lies to get attention from me or to get clicks & I don’t want to encourage that. 2) I’ve read a hundred rumors this morning. ONE of them is half-true. So I don’t want to be used as a way for people to throw nonsense at the wall until something sticks. 3) I’m storyboarding Superman Legacy and don’t have the time! Have a great day!”

In addition to calling out the attention seekers on Twitter, the biggest revelation from Gunn’s tweet has to be that he’s storyboarding Superman: Legacy. We knew that he was in pre-production on the film, but storyboarding means that we’re one step closer to having his vision fully realized.
