Much of the first trailer for “Star Trek: Discovery” was set on a bridge, but showrunners Aaron Harberts and Gretchen J. Berg tell EW that it’s not the bridge of the titular ship – that has yet to appear.

Instead, we saw the bridge of the U.S.S. Shenzhou, a very different and older Starfleet ship which is why you see Michelle Yeoh as Captain (as opposed to Jason Isaacs who is the confirmed Captain of the Discovery).

The series, which now finally has a September 24th premiere date, was delayed from an early in the year launch due to several issues. Part of that is an expanded episode order, but Harberts says the sheer scale of the world building the show is trying to accomplish is also partly to blame:

“There’s is so much artistry and custom craftsmanship that go into every prop, every costume, every set. These things have to be designed and manufactured. We flew a costume designer to Switzerland to pick up the fabric for the Starfleet uniforms. Several items on our uniforms are 3D printed. Some of our sets can take over six weeks to make. CBS has given us the time and the money to make something the fans will find worthwhile.” Berg adds: “You can’t cut corners or have 95 percent of what’s on screen be completely original and inspired and then have five percent something you bought at a store. It has to be cohesive — and it is. I’m so proud of what’s on screen, it’s so beautiful and it’s taking world-building to a whole new level.”

In a separate interview the other week with Collider, executive producer Alex Kurtzman spoke about former showrunner Bryan Fuller’s exit and how much of his fingerprints were left on the Trek series:

“Absolutely there are footprints left on the show. Someone once described Bryan to me as a unicorn and that’s just the truth. He’s a one of a kind writer. He’s just unbelievably brilliant and I really, really loved working with him and I loved seeing the way that his mind worked. Bryan was very involved in American Gods and I think that the scope and scale of what Trek has become made it so that Bryan elected to say, ‘I don’t wanna short-change either of these two things,’ they’re both sort of beloved to him, so we sat down and we figured out how are we going to take what we can have of you and continue that through not only this season of Trek but hopefully set up things that are coming next season. So much of what’s there in terms of story and certainly in terms of set-up, character, big ideas, the big movement of the season, that’s all stuff that Bryan and I talked about.”

The series will air in two blocks with the first starting from Sunday September 24th on CBS All Access and overseas on Netflix.
