I'm not sure if this has already been mentioned here, but Joss Whedon (BtVS head honcho) has a new venture which is available free up until Sunday 20th July - Dr Horribles' Musical Blog. The first 2 parts are available now (www.drhorrible.com) & are very good. Part 3 will go up on Saturday 19th.
If you liked 'Once More With Feeling' then you'll love this.
(I have no connection whatever with this, just thought there must be other Joss Whedon fans here who may not be aware of the existence of 'Dr Horrible').
