Speaking of busty blondes, here's one who knows how to act: Tawnya Manion, star of Power Girl: The Classifieds. Don't miss the cameo appearance of Blue Beetle, Booster Gold, and Star-Spangled Kid at the 7:55 mark.
The story continues in I'm Power Girl, Dammit!, which manages to cram more awesome into less runtime.
The guy who did both of these films, Chris Notarile, has a bunch more on his website.
Hey, people at DC Comics and Warner Brothers Pictures! GIVE THIS MAN A JOB!
