The following year, Lloyd joined a repertory company called the Palace Players, based at the Gaiety Theatre in Douglas, on the Isle of Mann.
[1] In 1951, Lloyd joined the rep comedy at the David Garrick Theatre in Lichfield, appearing alongside Lionel Jeffries in a variety of plays, such as The Recruiting Officer and The Bishop Misbehaves.
In August of that year, Lloyd played a doctor in the John Perry melodrama A Man About the House, earning him a positive review in the Lichfield Mercury.
In February 1952, Lloyd gave his first performance on London's West End, appearing in the first run of the murder-thriller Silent Warning at the Watergate Theatre.
[3] As an outside broadcast producer he supervised live coverage of many important sporting events such as the 1959 Wimbledon Championships, the 1960 Eurovision Song Contest, a World Cup qualifying match between England and Luxembourg, and Winston Churchill's state funeral.
[3] Lloyd began his tenure as Doctor Who's producer by overseeing the production of scripts that his predecessor John Wiles and former story editor Donald Tosh had commissioned.
[3] Lloyd and the newly hired story editor Gerry Davis oversaw the completion of the scripts as the serials The Celestial Toymaker and The Gunfighters, which both ran in 1966.
To that end, Lloyd oversaw the replacement of astronaut Steven Taylor and orphan Dodo Chaplet as the companions of the Doctor, introducing contemporary Ben Jackson and Polly Wright in their place.
Lloyd and story editor Gerry Davis came up with an intriguing way of writing the Doctor out – as he was an alien being, they decided that he would have the power to change his body when it became worn out or seriously injured.
Bennett's An Englishman Abroad told the remarkable true story of the chance meeting between actress Coral Browne (playing herself) and spy Guy Burgess (Alan Bates) in Moscow in 1958, while A Question of Attribution (finished shortly before Lloyd's death)[11] was a logical sequel, showing the radically different fate of Surveyor of the Queen's Pictures and fellow traitor Anthony Blunt.
