I have to say, I think this is the first time I've completely and honestly disagreed with Bob, in either Big Picture or Escape to the movies. I mean, we haven't always seen perfectly eye to eye (while it was definitely sub-par, I didn't hate The Expendables nearly as vehemently as you did, for instance) but I've always agreed with your general points, or at least understood where you were coming from.
But this? This is absolute garbage. I'm half expecting a "gotcha" big picture next week talking about how your really not THIS thick.
Gonna use a few examples from your bit here, and lets start with Thor. I'm assuming your Black-Thor picture was a reference to Idris Elba as Heimdall in the new Thor flick. As someone who reviews movies for a LIVING, I kinda expected a little better insight into the workings of Hollywood, but I'll lay it out for you. Hollywood didn't pick a black man for a white role because Elba fits the role perfectly or because of his great chops (don't get me wrong, loved him in Wire, not a fan of his other works though.) No. Hollywood picked a black man for a white role, in order to increase the ticket sales to black people, and as a nice added bonus, to give a little "controversy" and free publicity to the thing. The problem is, no amount of good story writing or superb acting is going to make him feel like anything more than "token black guy" in a role that he REALLY shouldn't be in. How about this: show me a movie about Shango, with the lead role going to Justin Beiber or some-such, and see the reactions you get.
Flip side: Mr Jackson as Nick Fury. Doesn't really bother me. Nothing about Fury's character seemed particularly "white" to me. Samuel L Jackson is a good actor and lends credence to the part. Plus the comic writers planned it out and did the swap well in advance, in the comics. Another one, Michael Clark Duncan as Kingpin in the Daredevil movie. Okay, so the movie wasn't all the great, but Kingpin was originally a white character. MCD fit the role in every physical way except the melanin level, plus the man is a great actor, so away you go.
