A threequel is most elementary—at least if you ask Jude Law.
The 40-year-old British star, who plays Dr. John Watson to Robert Downey Jr.'s Sherlock Holmes, has revealed that a third installment to director Guy Ritchie's film series based on Sir Arthur Conan Doyle's eccentric London detective could be in the offing.
"We had a meeting earlier this year, the three of us, and I think it's being written now," Law told Digital Spy recently. "Warner Bros. have still got to agree to pay for it…I think they want to!"
Another Sherlock Holmes mystery hasn't officially been announced yet. But Richie did sign a deal to helm a new entry last year and is reportedly interested in shooting in Los Angeles.
And to that end, according to the site, producers have tapped screenwriter Drew Pearce to get to cracking on the script.
Either way however, development on a sequel to 2011's Sherlock Holmes: A Game of Shadows is likely to take awhile given Downey's busy schedule.
After starring in 2012's The Avengers and this summer's mega-hit Iron Man 3, the 48-year-old actor is now filming Jon Favreau's comedy, Chef, and still has shooting to look forward to on The Avengers follow up, Age of Ultron.
As for Law, before he can reprise his role as Holmes' sidekick and solve some more crimes, he's got his own slate to maintain, not least of which is Dom Hemingway, a black comedy-crime drama in which he plays a very funny—and dangerous—safecracker opposite Richard E. Grant.
He also has a plum role in West Anderson's upcoming comedy, The Grand Budapest Hotel, about the employees of a famed 1920s European hotel.
