French In Action is now available for free, online. (click on the "VoD" link to the right of each episode; free registration required ) Long a staple of high school French classes and late-night PBS broadcasts, French In Action is notable for teaching French without translating it; meaning is made clear through context and repetition. It's an approach some people find useless and others consider "so excellent it almost justifies the invention of television ". If you'd rather learn Spanish, there's Destinos and for German, there's Fokus Deutsch--but neither one features Valérie Allain, subject of intense fascination (and occasionally creepy obsession.) ( Unfortunately, free streaming of French in Action doesn't seem to be available outside the US and Canada; Destinos and Fokus Deutsch have no such restrictions.)
