Hollywood star Eddie Redmayne and British astronaut Tim Peake will collect honours from the Queen today.
The pair are among the recipients at an investiture ceremony taking place at Windsor Castle.
Oscar winner Redmayne, 34, is being awarded an OBE for services to drama, while Major Peake, 44, was recommended for Companion of the Order of St Michael and St George.
Redmayne was named in the Queen's Birthday Honours list in June 2015 - a career-defining year for the star in which he picked up an Academy Award for his portrayal of Professor Stephen Hawking in The Theory Of Everything.
The actor, who was in the same year as the Duke of Cambridge at Eton College, is currently starring in Harry Potter inspired film Fantastic Beasts And Where To Find Them.
One of Britain's top heartthrobs, Redmayne married long-term girlfriend Hannah Bagshawe in December 2014, and the couple have a baby daughter called Iris May.
Meanwhile, Major Peake set another record when he became the first person to be named in the Queen's Birthday Honours while in space.
He was aboard the International Space Station (ISS) when he received the call informing him of his recommendation for Companion of the Order of St Michael and St George.
Eight days before his return to Earth, he spoke of his delight, and dedicated the award to those who had made his mission possible.
Major Peake, who has been recognised for services to space research and scientific education, became the first British person to walk in space on January 15.
He said the walk had been the highlight of his six-month mission, which began on December 15 last year.
Major Peake landed back on Earth on the steppes of Kazakhstan on June 18.
During his mission, he conducted more than 100 scientific experiments, engaged with thousands of schoolchildren on Earth, and became the first person to run the London marathon in space.
