Lung Chun-Erh (a.k.a., Doris Lung)
Lung Chun-Erh was in a remarkable number of Taiwanese KF films from the early '70s to the early '80s, including a film alongside Jackie Chan (Half a Loaf of Kung Fu). However, there are surprisingly few short clips featuring her on YouTube, and apparently no showcase clips.
She appeared to have learned MA strictly for the movies, and while clearly nowhere near as skillful as, say, an Angela Mao, her screen fighting was certainly passable, and she had the requisite 'intent'. Unfortunately, after she attempted suicide three different times, directors became reluctant to work with her, and sometime in the late 1980s, her arrest for shoplifting made news in Taiwan. I wish her the best.
Many of her movies can be seen online, but this clip from Kid's Ace in the Hole (a.k.a., Fighting Ace) is the only *brief* clip I could find of her clearly in action, even though she's not the featured fighter.
