Destinos: An Introduction to Spanish
26 hours of video programming giving you a beginner's course in Spanish, originally created by WGBH Boston in 1992. It's a little dated, but the language learning is still perfectly useful. The videos show many everyday situations in Mexico, giving students an ear for authentic accents. The "telenovelas" it features also weave together into a larger, mysterious story.
If it is to be used in a classroom, you'll need a license, but it is free for individual use.
