Robert Downey Jr. recently surprised fans when he revealed that Sherlock Holmes 3 is not only still on, but it could very well begin filming this fall. And now the franchise’s producer has chimed in, reiterating Downey Jr.’s optimism about potentially heading into production this year, while also revealing that it might not be the last sequel in the series.

Sherlock Holmes producer Joel Silver is currently out promoting The Nice Guys, the new dark comedy he produced for Shane Black (which you should totally go see this weekend). While speaking with Collider, Silver also addressed the potential for Sherlock Holmes 3 to begin filming this year, and he seems quite optimistic:

It looks like it could happen this fall. Downey said he wants to do it. He’s gotta launch into another Avengers movie, right after the New Year, so we’re trying to get it done. We have a script that we like. Jude [Law] is available and Downey is available, and we’re hoping we can get it done. If it works, great. If not, we’ll do it another time. But, it looks like it could happen now.

I really like his casual attitude about the project — eh, if we can do this year, cool. If not, we’ll do it later. No big deal.

Obviously, the key here is scheduling, and it looks like Downey Jr. has a window of availability later this year, if the script is complete by then. James Coyne was recently tapped to write a new screenplay for the sequel, following Iron Man 3 scribe Drew Pearce’s previous draft. As for director Guy Ritchie, he’s been trying to wrap things up on Knights of the Roundtable: King Arthur, another potential franchise-starter for Warner Bros.

While it’s not 100 percent official, it looks like Sherlock Holmes 3 will probably begin filming later this year. And according to Silver, it might not be the detective’s final outing — more sequels may be afoot:

I hope [it’s not the last one]. I don’t think so. How many Bond films have they made? As long as there’s a character, we can work with it. It’s not an end story. We can keep going, as long as people want to do it. It’s [the actor’s] call. They have to say, ‘Okay, I’m ready to go.’ I read about them making another Bad Boys. If they want to do it, then you try to get it done.

That’s a great attitude to have: instead of rushing to get sequel after sequel in theaters, Silver & Co. seem content with making more Sherlock Holmes movies when everyone has the time and actually wants to do it. Hopefully that approach will give us a great new sequel.
