Benedict Cumberbatch admitted that he needs to lose weight and the athletic body he had built up to complement his 'Doctor Strange' character. The Marvel Hero is perfectly in shape but needs a slimmer body to complement the private detective role he's playing in the Sherlock series.

Stressing on the need to get back on the "Sherlock body", the British actor explained, "I was in Doctor Strange shape so I was quite big! I was chunky - in a healthy way, an athletic way - and he's not necessarily, Sherlock."

The 40-year-old English actor also talked about the unprecedented worlds of the movies he's been dealing with and said he finds it difficult to believe the amount of 'real element' that is considered and applied in the Marvel world of which he's been a part of. The actor said, "I finished on Doctor Strange and, that night, I got on a plane. The next morning, I woke up and was driven to Cardiff."

"You're still often flying around on wires in front of a green screen, but there's a huge amount of set builds - it's phenomenal", the star added.

After bulking up for Doctor Strange, Benedict is planning to walk the leaner side to play Sherlock Holmes but has no specific time break to spin easily between the roles. Benedict's busy schedule requires the actor to lose weight as soon as possible for its been reported that filming of the series had already begun.

As the fans are looking forward to the new Sherlock series, the actor has a real pressure on him to lose weight and make a grand comeback. The upcoming fourth series of Sherlock is said to raise curtains from the prevailing mysteries with new twists and is one of the most awaited series of the television.

Cumberbatch will be making a comeback on the screen with his most popular TV series Sherlock on the New Year's Day on BBC One at 8 pm.
