While busy promoting his latest film "The Man from U.N.C.L.E.", screenplay writer and producer Lionel Wigram had some few words regarding the Sherlock Holmes movie series.

The 53-year-old Brit told IGN that "Sherlock Holmes 3" could push through if he and his team, which includes director Guy Ritchie, could figure out a stellar script for Holmes and Dr. Watson in their third movie outing.

"We're working on a Sherlock Holmes 3 script. I think we would all love to do one if we could come up with something that really was really going to knock it out of the park and was going to be the best of the three. So we're working on that - it's quite hard to do," said Wigram.

It can be remembered that "Sherlock Holmes" received rave reviews back in 2009. It garnered a 70% rating in the Tomatometer. It also scored 7.6 out of 10 stars in IMDb en route to a domestic earning of $210 million.

However, its 2011 sequel "Sherlock Holmes: Game of Shadows" wasn't held with the same esteem and was the inferior one of the pair. The sequel even earned less than its predecessor. It only managed to gross $187 million in the U.S.

Be that as it may, "Game of Shadows" performed relatively average in the box office and wasn't really considered a movie flop. Wigram and Ritchie, if he is still on board to direct, could also build around its ending as a launching pad for the third Sherlock Holmes movie.

As Cinema Blend pointed out, "The last movie left Sherlock Holmes in the standard Sherlock cliffhanger situation, having tumbled down the Reichenbach Falls with Professor Moriarty, so the first thing they'll have to do in the script is explain how Sherlock survived."

Fans will have to wait for further details on whether the third Sherlock Homes movie will materialize or not, although Wigram has stated that Robert Downey Jr. and Jude Law are "very very" amenable in reprising their roles.

Law spoke with Empire two years back and said there are plans for "Sherlock Holmes 3" but it was moving slowly.

"I think Warners want it and there's a lot of want from us as a team. We want it to be better than the other two. We want to make sure it's smarter and cleverer, but in the same realm, said the "Spy" actor in 2013.

Robert Downey Jr. was coming off the heels of "Iron Man 3" at that time to which Law referenced, "It's a slow process. We're all busy. So getting us together to try to nail that has taken a little bit longer than we had hoped."
