During his education, Llewelyn gained renown as a skilled sportsman, particularly as a rugby player and he remained a fan of the game throughout his life.

In 1940 his unit was engaged in fighting an entire Panzer division for several days near the French city of Lille, but they were overrun in attempting to retreat to Dunkirk, and Llewelyn was captured.

[7] After the war, Llewelyn continued his career as an actor, returning to television work in Sir Robert Atkins' 1946 film of A Midsummer Night's Dream.

"[9] In 1967, Llewelyn portrayed 'Q' alongside Lois Maxwell's Miss Moneypenny in an EON produced television documentary entitled Welcome to Japan, Mr.

Llewellyn continued to act in other roles throughout his tenure as 'Q', notably appearing the 1963 film Cleopatra (as a Roman senator), and the 1981 PBS production of Dr. Jekyll and Mr. Hyde, and he had a small role in the musical Chitty Chitty Bang Bang (1968), which was itself based on a children's book by Bond author Ian Fleming.

Llewelyn would also appear as Geoffrey Maddocks ('The Colonel') in the British television series Follyfoot from 1971 to 1973, and the BBC Wales production The Life and Times of David Lloyd George with Philip Madoc.

[10] He was the subject of This Is Your Life in 1995 when he was surprised by Michael Aspel at London's Hyde Park Hotel, during a press launch for the new Bond film, GoldenEye.

Despite playing an inventor in the Bond films, Llewelyn always maintained that he was totally lost in the world of technology, a trait that also plagued his successors, John Cleese and Ben Whishaw.

On 19 December 1999, Llewelyn was driving alone from a book signing event when his Renault Mégane collided head-on with a Fiat Bravo on the A27 near the village of Berwick, East Sussex.

Llewelyn sustained massive internal injuries and was airlifted by helicopter to Eastbourne District General Hospital, where he died soon afterward at the age of 85.

Roger Moore, who starred with Llewelyn in six of his seven Bond films, spoke at his funeral on 6 January 2000[13] at St Mary the Virgin Church in Battle, Sussex.
