Regal: Oliver Chris looked anything but the joker from Green Wing when he headed out onto the set of new BBC drama King Charles III in Beverley on Thursday as HRH Prince William
Oliver has been cast as the second-in-line to the throne in the BBC's adaption of Mike Bartlett's award-winning alternative future history play.
The actor, who has appeared in the likes of The Office and The Other Boleyn Girl, was dressed in the Prince's ceremonial military attire - which he wore on his wedding day.
Oliver's version of the distinctive Guards tunic featured was a near identical image, which featured the intricate collar which bears a shamrock.
Also clear to see on the jacket were the medals of rank, which signify the Princes place in the order of battle, as well as sporting the Garter Star and other honourary paraphernalia.

The Queen appointed William to the honorary rank of Colonel of the 1st Bn Irish Guards before his wedding, but it seems that in the future timeline the Prince has risen through the ranks.
The military ensemble was finished off by a pair of dress trousers, white shirt, black oxford lace-ups and a blue air force sash.
Oliver was also spotted on set at Beverley Minster with his co-star Margot Leicester, who plays the Duchess of Cornwall.

Caught in the elements: The actress was wrapped up against the cold in a long quilted jacket, though she sported a glittering tiara on top of her coiffed hair.

The two stars were joined by two other actresses, one of which bore a striking resmeblance to the late Princess of Wales, Diana - who appears in the play as a ghost before both Charles and William.
The other was dolled out in a white sleeveless ballgown, which she wore with a small tiara placed upon her head.

It's possible that the actress is taking on the role of Jess Edwards, who plays Prince Harry's (Richard Goulding) love-interest in the play.
The cast and crew are currently on-location in Hull, and are believed to be using Beverley Minster as a double for Westminster Abbey.
The scenes filmed in Yorkshire are the first time the cast have been seen together at work, following the official announcement of roles last week for the first major broadcast drama featuring the royals.

His beloved: Charlotte Riley stars as the Duchess of Cambridge, Kate Middleton, in the drama
The inventive drama sees the new king refuse to sign a controversial bill causing political chaos, rioting on the streets and a tank in front of Buckingham Palace.
The 90-minute one-off programme is based on the Laurence Olivier award-winning 2014 play of the same name.
Charlotte Riley stars as Kate Middleton in the drama, while Tim Pigott-Smith reprises the role he played in the award-winning play, King Charles III.
