Harris told MTV, "Apparently they're making a 'Dr. Horrible' sequel, a feature film I hope… I hope they cast me in it… We'll see."

Harris added, "I don't know what scale, they're talking all options, because they made the first 'Dr. Horrible' in five days on no budget at all… You don't want to make the feature film be an $80 million giant movie, because it defeats the purpose of what the first film was made to be, but then again you don't want it to be so low brow that it's not worth paying money to see as a movie…I don't think it will be on the internet, I think it will probably be a film."

Penned by "Buffy the Vampire" scribe Joss Whedon and Maurissa Tancharoen, "Dr. Horrible" featured Harris in the title role as "a low-rent super villain" wannabe. The series also featured Nathan Fillion as the superhero Captain Hammer and Felicia Day as Penny, the object of Dr. Horrible's affection. The series premiered July 15, 2008.

Music and lyrics for the series were penned by Joss and Jed Whedon, with additional lyrics by Maurissa Tancharoen. Joss Whedon is also responsible for creating the cult-favorite musical episode of "Buffy the Vampire Slayer," entitled "Once More with Feeling."

The series was produced on a shoestring budget over a period of six days during the screenwriters' strike. Three episodes, roughly ten-minutes each, were filmed. Neil Patrick Harris' Broadway credits include Assassins, Proof and Cabaret as well as the L.A. company of Rent, the Reprise! and New York Philharmonic productions of Sweeney Todd and the London mounting of tick, tick . . . BOOM! Harris is also well known for his television work on "How I Met Your Mother" and "Doogie Howser, M.D."
