From Variety:
Joss Whedon shared an eye-opening fact during Saturday night’s reunion of the “Dr. Horrible’s Sing-Along Blog†team: He’s made more money from his independently financed 2008 Internet musical than he did from writing and directing Marvel’s first blockbuster “Avengers†movie.
That’s pretty amazing considering he would have picked up between $5 and $10 million for writing and directing that first Avenger’s movie.
I previously wrote of Dr Horrible’s Singalong Blog in February 2009, where I discussed where the income was coming from. The iTunes revenue and DVD sales must have been pretty good as streaming served more as promotion for the iTunes and DVD sales.
