As tends to be the case with major casting announcements, Marvel and ABC got ahead of The Inhumans curve to reveal its major players before they could be identified on set by prying fans. That said, pry away into Black Bolt’s costume, and a CG Lockjaw stand-in with these first photos!

Reel News Hawaii got a hold of our first looks at filming, which offer a surprisingly clear look at Hell on Wheels star Anson Mount outfitted (sans tuning fork mask) as the expressive, but silent Blackagar Boltagon (really). And, I suppose if you’re going to incorporate a 2000-pound teleporting dog, you’ll want something on set to at least approximate the behemoth’s size:

In addition to Anson Mount as King Black Bolt, Marvel’s ABC Inhumans features Game of Thrones star Iwan Rheon as his brother Maximus, Serinda Swan as his Queen Medusa, and Ken Leung as advisor Karnak. Further cast includes Isabelle Cornish as Medusa’s sister Crystal, Eme Ikwuakor as Gorgon, Mike Moh as Triton, Sonya Balmores as Auran, and Ellen Woglom as an undisclosed human character.

Thus far of Marvel’s The Inhumans, we know that Iron Fist alum Scott Buck will showrun the series for Marvel and ABC, which have already set a September IMAX premiere for its first two episodes. Roel Reine has signed on to direct the first two episodes as casting concludes (not for Vin Diesel, who still isn’t keen on the TV bit), while has Marvel not clarified what, if any relationship The Inhumans will have to other MCU TV series.

We’ve still a few months before The Inhumans hits IMAX, but what do we think so far?
