Sherlock Holmes: A Game of Shadows is a 2011 British-American action mystery movie that was directed by Guy Ritchie and produced by Joel Silver, Lionel Wigram, Susan Downey, and Dan Lin. This is a continuation to the 2009 movie Sherlock Holmes, based on the same character role made by Sir Arthur Conan Doyle. The screenplay is by Kieran Mulroney and Michele Mulroney. Robert Downey, Jr. and Jude Law reprise their roles as Sherlock Holmes and Dr. John Watson, respectively, as the duo joint forces to outwit and bring downfall to their most cunning adversary, Professor Moriarty, played by Jared Harris.
Sherlock Holmes (Robert Downey, Jr.) is inquiring in to a seemingly unrelated series of crimes around Europe, believing all of them connected to Professor James Moriarty (Jared Harris), a criminal mastermind as clever as Holmes. After Moriarty arranges for another assassination, they poisons Irene Adler (Rachel McAdams), as her feelings for Holmes have compromised her usefulness. Meanwhile Holmes takes Dr. Watson (Jude Law) out along with his father Mycroft (Stephen Fry) for his stag party and saves another intended victim of Moriarty's, a fortune telling gypsy named Sim (Noomi Rapace). Holmes meets with Moriarty, who warns Holmes that if they persists in inquiring in to him, Watson will become a target. Holmes stows away on the train taking Watson and his new spouse Mary (Kelly Reilly) to their honeymoon location, knocking Mary off the train to the safe hands of Mycroft while they and Watson battle Moriarty's men. Holmes tells Sim that Moriarty targeted her due to her father Rene's work with him and he was a loose finish.
In Paris, Holmes, Watson and Sim go to the opera where they think Moriarty will strike, but Holmes realizes late that Moriarty has deceived him, as well as a hotel is blown up. As Holmes looks over the bodies, they realizes the bomb was a cover for a gunman of Moriarty's, Colonel Sebastian Moran (Paul Anderson) to shoot a specific visitor at the party. Tracking the man's possession of an arms factory in Spain which has recently had a massive number of shares bought by Moriarty, Holmes and Watson inquire in to but Holmes is captured. Moriarty reveals they owns shares in companies across Europe in cotton, guns and other goods and designs to start a war that will generate a massive demand for them and make him a fortune. Watson rescues Holmes and the escape the factory on a passing train. Holmes surmises Moriarty's next target is a peace summit, where they will generate an incident between world leaders to spark war.
At the summit with Mycroft, Holmes deduces that a set of twins working for Moriarty are not actually twins, and was an experiment to give a man the face of another. Realizing that Rene has been made to look like of the party guests and will act on Moriarty's behalf, Watson andSim find out which visitor they is while Holmes invites Moriarty to a game of chess on a balcony over a waterfall. Watson and Sim successfully cease Rene, but they is killed by Moran. Meanwhile Holmes reveals to Moriarty that in Spain they stole an account book tracing all of Moriarty's assets, the only piece of facts linking him to his deeds, and Mary has taken it back to London where Inspector Lestrade (Eddie Marsan) is confiscating them. Holmes and Moriarty mentally plan a battle that both recognize Holmes will lose, and with no other option Holmes blows soot from his pipe in Moriarty's eyes, distracting him so Holmes can grab him and knock the both of them off the balcony and in to the waterfall. Some time later, Watson and Mary prepare to go on another honeymoon while Watson finishes writing of his last case with Holmes. A delivery of an oxygen breathing device of Mycroft's alerts Watson that Holmes survived, and they runs to query Mary about the delivery while Holmes reveals himself concealed in Watson's room.
