There are a few things in particular Doctor Strange fans are hoping to see when Marvel’s mystical superhero film arrives next fall, including characters like the Ancient One and Night Nurse, as well as more familiar elements from the comics. Like the Sanctum Sanctorum, a structure built on sacred ground and charged with supernatural energy— and the place that Stephen Strange calls home. And the latest set photo may very well be taken from inside that house.

Marvel co-president Louis D’Esposito posted this photo of himself posing with director Scott Derrickson and producer Stephen Broussard:

That seal on the door on the left side may seem familiar to Doctor Strange fans: it’s the Seal of the Vishanti, a sign of powerful white magic, and it’s a part of Strange’s Sanctum Sanctorum in the comics. The object on the table looks as though it could be the Eye of Agamotto, which Strange used to defeat Dormammu — but that may just be an easter egg, of course.

The Sanctum Sanctorum is a townhouse built on grounds previously used for pagan and old Native American rituals, and as such is imbued with great supernatural power. The house itself is alive and actively attracts magic, often changing its layout at will. And like the Doctor’s TARDIS on Doctor Who, the home is much bigger on the inside.

In addition to the new set photo, Scott Derrickson’s Sinister scribe C. Robert Cargill has confirmed that he’s been working with Derrickson on the screenplay, which was previously penned by Jon Spaihts (Prometheus).

Doctor Strange stars Benedict Cumberbatch as the Sorcerer Supreme, Chiwetel Ejiofor as Baron Mordo, Tilda Swinton as the Ancient One and Michael Stuhlbarg as Dr. Nicodemus West, along with Rachel McAdams, Mads Mikkelsen, Amy Landecker (Transparent) and action star Scott Adkins in mystery roles — though it’s been rumored that McAdams is likely playing Night Nurse.

Doctor Strange hits theaters on November 4, 2016.
