(W) Joss Whedon. Neil Patrick Harris stars as Billy, a.k.a. Dr. Horrible, a budding super-villain whose plans for world domination continually go awry.

This book has been compiled by Joss Whedon and his team, and features brand new, specially-written behind-the-scenes material, unseen photos, the script, and the sheet music that fans have been demanding!
