Here is the complete Youtube playlist for the Yale course "Game Theory", lectured by Ben Polak. 24 lectures in total, about 1 h 15 min each.
Course description: This course is an introduction to game theory and strategic thinking. Ideas such as dominance, backward induction, Nash equilibrium, evolutionary stability, commitment, credibility, asymmetric information, adverse selection, and signaling are discussed and applied to games played in class and to examples drawn from economics, politics, the movies, and elsewhere.
I have had the intention of watching through this, but haven't had the time after the first few lectures. The material is recommended, though.
