Sherlock's Benedict Cumberbatch to perform one-off reading of Look Back in Anger -- I wish I could be there. I hope someone puts this on YouTube!!
Cumberbatch moments: Time Traveller Problems; Casual (Blue Jean) Batch and another Casual Batch; Anything will be held against you poster; ibelieveinmycroft offers Blond Batch when he's Peter Guillam from Tinker Tailor Soldier Spy... and Benedict smoking (obviously in smokers' jail, hmmm; maybe while filming Sherlock).
If audio Benedict is more your cuppa, there WAS a tumblr for that [link broken as of October 2013]. From that lovely source, I found that Benedict has read a Ngaio Marsh novel, Death in a White Tie; you can find that and other audio books via LiveJournal now. First, I highly recommend Dame Ngaio Marsh's mysteries, and second: WOW. You can also Google to get various YouTube readings, such as Jabberwocky and Kubla Khan, for starters.
Review of the unaired pilot for Sherlock; and another longer review of it over here.
After this point: Spoilers for season/series 2 until the final paragraph!
