"Mathematical Mystery Tour"

The BBC has done some great hour-long mathematical presentations. Recently, Cliff Pickover tweeted one of the old Horizon episodes (I've linked to before), called "Mathematical Mystery Tour." It's interesting with its discussion of "proof" in mathematics (in light of the post I did a bit ago over at MathTango), as well as other subjects. And though it's rather dated, still a worthwhile 50 mins. if you've missed it, and have some time:
