Downey won a Golden Globe in 2010 for his performance as Holmes in the first installment of the series, in which Holmes and Law’s Dr. Watson uncover a supernatural plot to expand the British Empire.

Downey is currently slated to star in “The Voyage of Dr. Dolittle” as the titular main character and will return to play Tony Stark in the sequel to “Avengers: Infinity War,” with both films due out next year.

Law, who will appear as Albus Dumbledore in Warner Bros.’ “Fantastic Beasts: The Crimes of Grindelwald,” is currently filming the Marvel Studios’ film “Captain Marvel,” which will hit theaters next March.
