Executive producer Steven Moffat recently revealed some teasers for the upcoming season of BBC's hit TV series, Sherlock, which including some characters getting more relevant roles in the upcoming installment.

Sherlock Theme Park Coming Soon?

Moffat recently revealed in an interview that having a woman on the show makes it much better.

"I think she's becoming quite an important part of the show," Moffat said. "One of the difficulties in adapting Sherlock Holmes... [is that] there are no women in Sherlock Holmes, the original stories. You really don't have the female perspective on them. And they're slightly flat when they turn up. And yet, every time we bring a woman into Sherlock, it works hugely well."

Sherlock to Return in 2016?

Moffat also described why having a female on the show is so important.

"A female perspective on that friendship and on that man is incredibly telling, incredibly illuminating," Moffat said. "So we've expanded hugely the part of Mrs. Hudson [played by Una Stubbs] because she didn't speak in the original. And we brought Molly in."

There was a recent announcement that Sherlock will get its own theme park in Portsmouth that will focus on the detective's adventures in Baker Street, London.

Steve Pitt from the Portsmouth Cultural Partnership is reportedly the one who brought up this idea.

"What we are talking about is a world class, Sherlock Holmes experience," Pitt said.

"It would be very interactive and high quality," Pitt added. "There are so many tie-ins around the legacy of Sherlock Holmes being 'born' in Portsmouth."

Sherlock Season 4 is expected to premiere in 2016.
