Dexter Fletcher directing 'Sherlock Holmes 3'

"Rocketman" helmer Dexter Fletcher has been roped in to direct Robert Downey Jr-fronted "Sherlock Holmes 3".

The previous two films in the franchise --"Sherlock Holmes" (2009) and "Sherlock Holmes: A Game of Shadows" -- were directed by Guy Ritchie.

According to Variety, Warner Bros has been planning to make a third film, but things could not work out due to Downey's busy schedule as Iron Man/Tony Stark.

The third installment in the mystery series is expected to hit theatres on December 21, 2021.

Chris Brancato is penning the script, while Susan Downey, Joel Silver, Dan Lin and Lionel Wigram are producing.

Jude Law is also suppose to return as Professor Watson.

The film will be a co-production between WB and Village Roadshow.
