Dame Judi Dench and Colin Firth, who earned their Oscars playing members of the monarchy, will be celebrated at a royal reception for British Academy Awards winners.
The Prince of Wales and Duchess of Cornwall will host a reception at St James's Palace on Wednesday to celebrate British filmmaking, which will also see Sir Michael Caine and Emma Thompson among the Oscar-winning guests from both in front of and behind the camera.
Academy president Cheryl Boone Isaacs, Academy CEO Dawn Hudson and members of the Academy's Board of Governors will also be in attendance.
More than 300 British artists and filmmakers have been awarded Oscars, with 45 years of film production represented at the reception.
Despite seven nominations, Dame Judi has only won one Academy Award, for best supporting actress for her eight-minute role as Elizabeth I in Shakespeare in Love.
Colin took home the best actor gong in 2010 for his role in The King's Speech as King George VI, Prince Charles' grandfather.
Sir Michael is only one of two actors - the other being Jack Nicholson - to have been nominated for an Oscar in every decade from the 1960s to 2000s, winning his first supporting actor award for Hannah and Her Sisters and his second for The Cider House Rules.
Emma has similarly picked up two awards: for best actress for Howards End and best adapted screenplay for Sense and Sensibility.
The 57-year-old actresses enjoyed a very different kind of reception recently when she was sprayed with manure by an irate farmer when she protested against fracking alongside her sister Sophie and members of Greenpeace at a farm in Lancashire.
The duo broke a court injunction to protest on the site, filming a Great British Bake Off parody, and although police were called, no arrests were made.
Fracking is likely to be a hot topic of conversation with Prince Charles, who is an outspoken voice on environmental issues and climate change.
