Now that the air date for one of the most sought-after series, "Sherlock," has been revealed, actor Benedict Cumberbatch who has played Sherlock Holmes since season 1 thinks that there might be a need for a break for the show after season 4 is completed.

According to a report from Telegraph, Cumberbatch recently said, "I think there will be a lull. I don't think it will be in a year and a half necessarily but we will wait and see and maybe it will be."

The famed British actor who recently had a successful Marvel debut as Doctor Strange reiterated that when the viewers have watched and understood "Sherlock" season 4, "they might go 'Oh yeah, maybe there does need to be a break now' because of what happens in it."

Speaking of Cumberbatch's role in "Doctor Strange," he clarified that if "Sherlock" season 5 would take a longer break than previous seasons usually did, his new Marvel stint has nothing to do with it. The actor said, "[Marvel] moved the schedule to accommodate Sherlock, there is a lot of mutual love between those two enterprises and there is no reason why one cancels out the other."

According to the actor, he initially turned down "Doctor Strange" because of his tight schedule, but Marvel "kept coming back" until they decided to adjust the movie's filming to suit Cumberbatch's schedule.

Late last month, the official trailer of "Sherlock" season 4 was featured in BBC sending very cryptic message to its fans, "Everything they know will be tested. Everyone they know is under threat." And if that is not chilling enough, the trailer ends with a very terrified look on Sherlock's face.

"Sherlock" is a crime drama TV series and contemporary adaptation of Sir Arthur Conan Doyle's detective-themed stories. Martin Freeman has been with Cumberbatch in "Sherlock" playing Dr. Watson. The series has been known for having just three episodes per installment.

"Sherlock" season 4 will air on Jan. 1, 2017 on BBC.
