Sorry, no, the movie isn't currently in the works.* That's what makes this the most self-indulgent post on the internet.
A few friends and I were discussing casting choices for our titles, should we ever be so lucky as to land a movie deal. (Which is similar to daydreaming about what we'd do with those mega-million lottery winnings, but way more fun.) Delusional or not, I thought I'd list them online for all the world to see. ("See" is, in this case, pronounced "laugh at.") Because, as McKinley would say, "That's the accommodating sort of repugnant ruffian I am."

Voiced by the one and only Benedict Cumberbatch. Because, of course.
