Goodnight Sweetheart is a British science fiction time travel sitcom, starring Nicholas Lyndhurst, created by Laurence Marks and Maurice Gran, and produced by the BBC.

[3] The sitcom premiered on BBC1 on 18 November 1993 and ran for six series until its conclusion on 28 June 1999, with repeats after this date being aired on ITV3, Gold, Drama, Yesterday and Forces TV on Sky Digital.

On attending a TV repair call-out in London's East End, Gary accidentally discovers a time portal at Duckett's Passage, which leads to wartime London, where he meets Phoebe Bamford, a pretty barmaid who works in the "Royal Oak" pub; her father Eric who runs the pub and Reg Deadman, a dim-witted but friendly policeman.

To ensure his visits do not interfere with history, Gary brings in assistance from Ron as a confidant, to aid him with problems and to supply him with 1940s five-pound notes and identity documents.

Phoebe eventually takes over the running of the Royal Oak after the death of her father Eric, later marrying Gary, despite him committing bigamy.

Yvonne becomes pregnant, only to suffer a miscarriage but she later becomes successful with her organic beauty products, opening a company and transforming into a millionaire, allowing her and Gary to own a luxury apartment.

Ron later faces a divorce, losing his home and control of his printing company, adding to Gary's problems, who[clarification needed] eventually allows him to have the lease for his Mayfair flat in the present.

Gary is resigned to being forced to stay with Phoebe and their son, though he writes a message behind a strip of wallpaper of his Mayfair flat, knowing that Ron is redecorating it in 1999.

The final episode of the original series cuts to Yvonne standing at the gates of Blitz 'n' Pieces, wondering whether or not they would meet again, before being joined by Ron.

The incident causes Gary to be thrown into the future in the 2010s, arriving in the men's toilets of a trendy burger joint in east London, where his former shop was.
