"Sherlock" cast Benedict Cumberbatch feels overwhelmed playing the role of "Richard III" as the actor shows no sign of slowing down even after getting engaged to Sophie Hunter.

The MailOnline published photos on the set of "The Hollow Crown" in Leeds Castle in Kent.

"His bedraggled look was a far cry from the regal appearance he made during earlier scenes filmed in October, suggesting the latest shoot depicted the end of the monarch's ill-fated two-year stint on the throne," it said. "Wearing a wig to match historical paintings of Richard III, who was killed in battle against his successor Henry VII, the star had his face bloodied by make-up artists before the cameras rolled."

In the new BBC show, "Sherlock" cast Benedict Cumberbatch will play King Richard III and he seems to be sinking into the role with his brown wig and armor.

The three-part mini-series will also star Dame Judy Dench as Duchess of York, Keeley Hawes as Queen Elizabeth and Sophie Okonedo ("Hotel Rwanda") will play Queen Margaret.

The "Star Trek: Into Darkness" actor recently got engaged to Sophie Hunter, the theather director not the "Game of Thrones" star.

The announcement was made in the form of an ad at The Times which the actor's parents paid for.

"Mr BT. Cumberbatch and Miss S.I. Hunter: The engagement is announced between Benedict, son of Wanda and Timothy Cumberbatch of London, and Sophie, daughter of Katharine Hunter of Edinburgh and Charles Hunter of London," the ad said.

When asked which character gave him more challenge, "Sherlock" cast Benedict Cumberbatch told journalist Jeffrey Brown. "Each one, each one, the next job is the most challenging character. The one I'm doing right now, Richard III, is the most challenging character I played."

"It means that the culture can obviously take reinterpretations of these great, great, iconic roles and also there's something in each, all of those performances that still draws people in," Benedict Cumberbatch added.
