Theoretically, Warner Bros. would be into a third match-up as well. The first installment in which Downey plays the title character, while Law takes on the role of Dr. John Watson, pulled in a massive $209 million-plus - and that was just in the U.S. The 2011 follow-up (both directed by Guy Ritchie incidentally) still cashed in with an impressive nearly $187 million domestically (and well-over a half-billion dollars worldwide).
So will it happen or not? Jude Law gave some insight, as reported by Metro in the U.K.
"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," he said. "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."
Apparently Iron Man 3 writer Drew Pearce was tapped to complete a script for the possible third installment. Law is currently promoting his latest film, Anna Karenina where it debuted last at the Toronto International Film Festival.
