Downey, Jr. and Law have enjoyed great success with their portrayals of the detective and his sidekick in Ritchie's all-action take on Sir Arthur Conan Doyle's creation, with the first two movies taking more than $1 billion at the box office.
Studio bosses are rumoured to be planning a third outing, and Law can't wait to get back in front of the camera alongside Downey, Jr.
He tells Collider.com, "There's certainly talk of it and I know there's a script being played around with, but Downey's a busy boy and I'm a busy boy so we'll see. But we want to (do another one). We're a very happy team and we have a lot of fun and we also think there's still a lot of legs in the duo."
