It’s elementary that you can deduce plot information from the scrutiny of movie stills – you just need enough of those stills.
Here are two more pieces of evidence to help you put together a casebook on Sherlock Holmes: A Game of Shadows, the upcoming Guy Ritchie-directed sequel. You may, just about, consider the second image to be a spoiler. So don’t look at it if you don’t want to.
The first of these was newly released to the film’s press kit, the second has been scanned from Empire magazine.
Now go buy Empire and read their coverage of the film to pay them back for having seen the image. Seems only fair.
