Danger 5, Series One
A group of "swinging 60s" young spies have one job -- Kill Hitler.
I don't know why, but I get the biggest kick out of Dario Russo and David Ashby's Danger 5. Series one appears to be set in the 1960s world of The Thunderbirds. And it stars Dario's father, Carmine Russo, as Adolf Hitler. Everything about this series is spot-on. All the voices are dubbed, including Hitler, who delivers his lines in English but is dubbed into German for the series.
Series two is set in the 80s and and has a slasher film vibe. Hitler is transformed into Johnny Hitler, the high school football star. Personally, I didn't enjoy series two nearly as much as series one. But this may simply be because I went to high school in the 1980s.
