I'm sorry, but please don't watch Doctor Strange when it comes out.
(I realize there's irony in just giving the trailer more hits, but...)
Casting a woman as the Ancient One? Yeah, sure, guys. But couldn't you have cast, I don't know, an Asian person? And it would have been really nice if you'd cast an actual Tibetan, for that matter (I doubt this casting choice was actually intended to cover up the nasty real-world bullshit (pardon my pottymouth) that Tibet's had to deal with over the last few decades [what with China taking them over, trying to take their name away, and killing a bunch of Tibetans]*, but yeah casting some white person is pretty crappy of you guys).
And as my sister has said, if you're going to cast someone to be Doctor Strange, it had darned well better be somebody who looks good with facial hair, not Benny D. Cobblingblock.
Best YouTube comment on the trailer:
Sadly, no, Robert Downey Jr. is not in this. He'd actually have made a pretty decent Doctor Strange, and then they could have done bluescreen gags with Strange and Tony Stark and everybody insisting they look alike and both of them going "no we don't, what are you talking about?"
...That's probably why I'll never make a Marvel movie.
*EDIT: Apparently my worldview is too optimistic because somebody... admitted that appeasing China was an actual intention behind the casting? Darnit you guys.
