After spending a decade giving intergalactic bad lads a kicking and bickering with Benedict Cumberbatch, Robert Downey Jr is heading back to Earth for the third film in the Sherlock Holmes series.

We don't have a name for the film yet, but Sherlock Holmes 3 is slated to open on 25 December 2020. Jude Law will be back as Dr Watson too, though there's no news yet on whether Guy Ritchie will return to direct. Narcos creator Chris Brancato is reportedly writing the script.

It's looking fairly likely that Professor Moriarty won't be returning, though. Jared Harris told Digital Spy: "I think the last iteration when they last wrote a screenplay for Sherlock Holmes 3, Moriarty wasn't in it. So, I'm not focusing on it."

Sherlock Holmes cemented Downey Jr's renaissance after Iron Man - the Robvival, if you will. Both the first film and its sequel Sherlock Holmes: A Game of Shadows took gargantuan sacks of cash, grossing $524 million and $545.4 million globally respectively.

However, up until now Marvel's relentless release schedules reportedly kept a third Holmes film from happening.

Christmas 2020 already looks pretty jammed with big releases, with James Cameron's Avatar 2 coming on 18 December.
