I think the TV inspiration, without the low kicks knees and punches, is from the Avengers two episodes spring to mind one where Emma defeats a gang of enemy agents in training if I remember right they are in leotards, filmed in black and white it is unusual as in most episodes she beats up hapless males, the other one is where Tara gets in a fight with an agent posing as a leotard wearing dance school teacher played by Penelope Keith of Good Life fame.
