[2][3] Each week saw the gang in a separate adventure, including episodes based around a runaway homemade hovercraft, a chocolate factory and invading 'Martians' with guns that shoot out chocolate candy, a disastrous camping holiday, collecting tin foil for a guide dog, becoming pop moguls with their protégé 'The Cool Cavalier', and a haunted stately home.

Some of the cast were unknown, though Melvyn Hayes was an established adult actor, Gillian Bailey was fairly experienced for a child actor and both Brinsley Forde and Michael Audreson had appeared in The Magnificent Six and a Half, a series of Children's Film Foundation films on which the Double Deckers were based.

[4] Peter Firth has gone on to a prominent acting career, appearing in Equus, The Hunt for Red October, Tess, Pearl Harbor and Spooks (known in some territories as MI-5).

Music played a prominent part in the programme, with an original soundtrack sung by the cast and written by Harry Booth, Melvyn Hayes and Johnny Arthey.

[3] In the United Kingdom, Here Come the Double Deckers was released in November 2010 by Second Sight as a two-disc Region 2 DVD set containing all 17 episodes.

Many of the crew members from the Six and a Half series also worked on the Double Deckers, including producer Roy Simpson, director and writer Harry Booth, writer Glyn Jones, and choreographer Arnold Taraborrelli (who designed the title cards for Six and a Half).

In addition, future Double Deckers cast members Brinsley Forde and Michael Audreson were among the stars of Six and a Half, and Melvyn Hayes appeared in a few episodes.
