Who Wrote Shakespeare's Plays?

Having been to lectures as a student on the subject of whether Francis Bacon, Christopher Marlowe or even Elizabeth I wrote them, I'm going to have to be boringly conventional and say that I think William Shakespeare probably wrote Shakespeare's plays. Still, it is good to see a bit of literary controversy being stirred up by the new film Anonymous (which looks from the trailer like a pretty third-rate rehash of every conspiracy theory ever mooted on the identity of the Bard). I only wish there had a been a more pro-active approach taken to the Da Vinci Code when members of the great British public were taking that fabrication as fact.
