I'm not sure how many ppl have seen this.. so I will post it anyway in the event you haven't.. This is a small web posted musical movie with Neil Patrick Harris as Dr. Horrible.. and also staring Nathan Fillion, from Fire Fly, and Serenity as Captain Hammer.. It is written and directed by Joss Whedon, and his brother..

There are 3 ACTs to this. You can either watch them one at a time, or all three together.

Enjoy.
