Benedict Cumberbatch. Chiwetel Ejiofor. Benedict Cumberbatch and Chiwetel Ejiofor. Two names you can roll around in your mouth like a scoop of peanut butter, and also, the hero and villain of Marvel’s upcoming Doctor Strange. (No “glove,†please — they’re British.) On Tuesday night, Cumberbatch stopped by Jimmy Kimmel’s show to unveil the first teaser trailer for the film, which showed off the Sorcerer Supreme in action for the first time. Yes, that’s his nickname — he’s the only Marvel superhero to also be a Taco Bell menu item.
