I saw Sherlock Holmes a while ago in Boston visiting my friend Liz, and we both ended up drooling over more than Robert Downey Jr. Both of us being RISD grads, the art at the end credits left us in our seats while audience rolled out. Here are some great screenshots I found on Graphic Exchange. The end sequence was done by a company called Prologue, which coincidentally enough, another RISD friend of mine used to work for in LA. You can read about their process and see more concepts at the post on Graphic Exchange.
Rachel McAdams was great in this role too - but I like all her stuff (a bit of a girl crush)
So, if you ever watch the movie stay tooned for the great work of art that is the end credits!
