Every Sherlock Holmes has a Watson. Most have a Moriarty. And quite a few have their Irene Adler.
And while we see actors move from role to role, production to production, it is rare to see a TV actor, especially a Holmes, move up into the big screen ranks to the point where he's acting opposite the fellow Holmes-stars of another Sherlock.
But that's what we saw today as Rachel McAdams, Robert Downey Jr. Sherlock's Irene Adler, got cast with Benedict Cumberbatch in Marvel's Dr. Strange. Watching Cumberbatch's rise in the movie industry has been great fun, but for pure geek-pleasure, seeing him cast as leading man opposite his rival Sherlock's Irene Adler is a pretty cool benchmark in the career of a Sherlock actor.
Of course, his Moriarty is now in Bond movies and his Watson . . . well, his Watson has been everywhere and will continue to be all over the place. But something about this particular pairing gives one hope that one day we might actually see a theatrical Benedict Cumberbatch Sherlock Holmes movie release.
Or maybe I'm just being the fanboy. Either way, Rachel McAdams and Benedict Cumberbatch in the same movie? I'll take it.
