Sherlock Holmes: A Game of Shadows and David Fincher’s adaptation of The Girl With The Dragon Tattoo are two of the biggest films being released during the 2011 Holiday season, and as late summer begins to transition into fall, the studios behind both films (Warner Bros. and Columbia Pictures, respectively) are setting their marketing campaigns in motion.

Today brings new images from both Sherlock Holmes 2 and Dragon Tattoo, featuring the films’ all-star casts, which include Robert Downey Jr., Jude Law, Daniel Craig, original girl with the dragon tattoo, Noomi Rapace, and new girl with the dragon tatoo, Rooney Mara.

First, let’s take a look at the new images for Sherlock Holmes: A Game of Shadows. In this sequel to director Guy Ritchie’s successful blockbuster re-imagining of Arthur Conan Doyle’s famous detective, we find Holmes (Downey) and Dr. Watson (Jude Law) facing off against their iconic nemesis, Professor Moriarty (Jared Harris). To win the day, Holmes and Watson get help from a cunning gypsy woman name Sim (Rapace).

The Girl With The Dragon Tattoo

In David Fincher’s adaptation of late author Stieg Larsson’s worldwide bestseller, disgraced journalist Mikael Blomkvist (Craig) leaves the hard-hitting news publication he calls home, in order to take on a contract assignment for a wealthy aging industrialist (Christopher Plummer). The assignment: solve a decades-old mystery involving the disappearance of the industrialist’s cherished niece – a case which opens the lid on a Pandora’s box of terrible family secrets. In the midst of this investigation, Blomkvist finds his case intertwining with the life of a Gothic young hacker named Lisbeth Salander (Mara), whose brilliant mind and fierce will may be the key to solving the mystery – and then, restoring Blomkvist’s lost honor.
