The folks at IGN just posted a brand-new one-sheet for Guy Ritchie’s upcoming “Sherlock Holmes.” This character poster entirely belongs to Rachel McAdams, who plays Irene Adler in the flick.

Robert Downey Jr. stars as Holmes, while Jude Law is on board as Watson. McAdams obviously plays his love interest, and Mark Strong will portray the villain.

“Sherlock” will make his way to the big screen Dec. 25, 2009. For the sake of it, I also posted the two previous character posters below. Enjoy!
