Back in September, Rachel McAdams told The Wrap that she has officially signed on as part of the cast of Marvel's Doctor Strange which is due to come out November 4, 2016. Joining Benedict Cumberbatch, Chiwetel Ejiofor, and Tilda Swinton, this is shaping up to be one hell of a cast, if you don't mind me saying. Though we're still uncertain as to what role she'll be playing, that hasn't stopped people from sharing their ideas, with many guessing Doctor Strange characters ranging from friend (Clea) to foe (Morgana). I'm here to address some of the characters that we may be overlooking as we look forward to a movie that won't be arriving for another year.
Now this may be quite the jump, based solely on the director's seemingly flippant tweet, but I think it's worth considering that McAdams could very well be the one who holds Thanos' cold, Titan-like heart: Lady Death! After Thanos' introduction in The Avengers post-credits scene (and, if we're honest, Guardians of the Galaxy, because that didn't show us much more of the Mad Titan), we know of his love for Lady Death. And if she was played by Rachel McAdams, could any of us blame him?
That is, unless you've been keeping up with Agents of S.H.I.E.L.D. and are of the camp that we've already seen Lady Death.
2. Ms. Marvel/Carol Danvers
Tell me I'm not the only one thinking this. While Ms. Marvel's origin is not connected to Doctor Strange in the comics, with Captain Marvel set to release March 8, 2019 and no mention of Mar-vell in the foreseeable future, I can only assume we'll see part of Carol Danvers' origin before becoming Captain Marvel at some point in the next few years. Her origins could even be altered slightly, involving Doctor Strange in helping her to become Captain Marvel through some path to the Kree or Inhumans (connecting to the wider Cinematic Universe, as well). Do you think Rachel McAdams could be our first look into Carol Danvers? Doubtful, yes. Possible? Let's hope so.
3. Spitfire/Lady Jacqueline Falsworth
Part vampire, full speedster and Brit, Spitfire leaves a trail of nonlethal fire wherever she goes. Her mutant abilities (if Quicksilver, Scarlet Witch, and Quake got around the rights issue, why couldn't she?) were triggered by a combination of a synthetic blood transfusion containing Horton Cells from the original Human Torch and being bit by a vampire. The only real way that I could see this happening is the fact that part of Doctor Strange is filming in London.
Is that enough evidence for Spitfire? Not at all; however, McAdams could fit the role rather well and this character could then bring us more from MI-13, Union Jack, Captain Britain, or our other British heroes. Heck, I would even be satisfied with a Blade reference. Not to mention, we no longer have a speedy character in the MCU.
We know McAdams can pull off the accent, but will this be her role in Doctor Strange? It's a long shot, but not out of the realm of possibilities.
4. Dagger/Tandy Bowen
She is a member of the New Warriors, Secret Avengers, and appropriately, the Secret Defenders (started by Doctor Strange himself). This fan favorite, partnered with Cloak, would be a welcome addition to the MCU. Both Cloak and Dagger gained powers after being injected with a designer drug, which triggered some latent mutant genetic factors (along with some magical interference by D'Spayre). This could fit in well with where we currently are in the MCU, dovetailing nicely with the New Warriors/Secret Avengers thing going on in Agents of S.H.I.E.L.D.
I'm hoping that this speculation turns out to be true, because it is a crazy guess, but not unfounded. In sort of a convoluted storyline from the comics, Odin takes both Valkyrie and Thor's powers, essentially turning them human (much like in Thor). Eventually, Odin reverses this and wipes their memories, but this idea could be used to introduce her into the MCU (albeit, slightly changed in order to make sense). Another possibility is when Amora the Enchantress captures her soul and pretends to be Valkyrie for a while. That even gives us the possibility that McAdams is actually just Amora playing games with Earth's heroes before heading to Thor: Ragnarok.
Valkyrie is a member of both the Secret Avengers and the Defenders, so she could not only serve as a bridge from the cosmic world of Asgard to the mystical world of Doctor Strange, but as a crossover character into other aspects of the MCU, as well (i.e. The Defenders, Thor: Ragnarok, etc.).
