Re: Robert Downey Jr in Castle's Television Promo!
I'm also hoping that this is a tease about Ant Man joining the Avengers soon and that Nathan Fillion will be playing him. The internet rumors have been saying this for a while. I would love to see Robert and Nathan do something together! "Hammer Man" (Nathan's character in Dr. Horrible's Sing A Long Blog) is like a...less brilliant Iron Man, but with the same irresistible cockiness!
