David D. Levine has been many things, including Hugo-winning short story writer and Martian explorer — but now he's taking on a new role: supervillain. Check out this brand new Dr. Horrible-esque video, in which he delivers a "Letter to the Editor" from the supervillain Dr. Talon, from his story in the anthology The Mad Scientist's Guide to World Domination.

And lest Dr. Talon hold us all to ransom with some kind of doomsday device, we should also mention that Levine's story collection Space Magic, including his Hugo-winning story "Tk'Tk'Tk," is finally out as an ebook.
