Speaking on BBC Radio 5 over the weekend Stephen Fry announced that he would be playing the role of Mycroft in the moving. They will start filming later this year.
The character of Mycroft is perfectly suited to the wonderful British comic, intellectual and actor. Mycroft is a more intellegent but lazier version of Holmes himself.
Speaking to Danny Baker he said "I'm playing Mycroft in the sequel to the Sherlock Holmes film Guy Ritchie directed with Robert Downey Jr and that sort of part is fun."
