"a touch of madness" [3GAB]Marketing blogger Chris Thilk keeps a site called Movie Marketing Madness, in which he summarizes and assesses the efforts of Hollywood in their creativity and execution around marketing new films.
As you can imagine, he's done his homework for the Warner Bros film Sherlock Holmes starring Robert Downey, Jr. and Jude Law, directed by Guy Ritchie. You can see previous mentions of the film on our site by clicking on this link.
Thilk includes in his assessment a mention of the posters, the trailers (yes, there were two), the online component - including the 221B game, the television advertising and cross-promotions such as 7-Eleven and the Visit Britain tie-in, and the TweetDeck theme.
In addition, there's an extensive section on press coverage, which very kindly lists the Baker Street Blog / I Hear of Sherlock Everywhere.
