Doctor Strange was recently released on Digital HD platforms around the globe. In addition to the Scott Derrickson flick, the package contains loads of special features, one of which is an exclusive sneak peek at Marvel Cinematic Universe Phase 3 that includes concept art for upcoming movies, including Thor: Ragnarok and Black Panther.

While the full preview has yet to make its way online, screenshots of some of the official artwork have surfaced via Twitter user @Marvel_Freshman. One of the pieces offers us something that we've been eagerly awaiting since the beginning of last year: Our first look at Cate Blanchett's Hela! We had previously seen some really cool fan art of the two-time Academy Award winner as the Thor: Ragnarok big baddie, but nothing beats this new one!

Another piece for the Taika Waititi flick teases an epic arena battle between Chris Hemsworth's Thor and Mark Ruffalo's Hulk. Check out the pieces below!

Some of the Black Panther artwork features Chadwick Boseman's titular superhero. Other pieces take us on a spectacular walk-through of the various Wakandan locations in the Ryan Coogler flick. Take a look:

Thor: Ragnarok is set to arrive in theaters on November 3, 2017, but we haven't seen any footage from the movie yet. Perhaps Marvel Studios would prefer to launch the first trailer with the theatrical cut of Guardians of the Galaxy Vol. 2 in May.

Black Panther has recently started filming, but won’t be released until February 16, 2018. It's highly unlikely that the studio would release any promotional content for the movie during the next six months or so.

Share your thoughts about the new batch of Thor: Ragnarok and Black Panther concept art, and stay tuned for the latest updates!
