A few weeks ago, accidentally, I found this you tube channel. It is from Yale University and those of you who have not the luck to go directly to Yale, you will find several lectures concerning a variety of themes on their yt channel. For example, Robert Shiller explaining "option pricing" (that is where the title is from).
I can really recommend those lectures, not just because of the content, which is - needles to say - interesting, but especially because of the lecturers.
