Best known for playing Del Boy's hapless little brother Rodney Trotter in Only Fools And Horses, Lyndhurst is set to play Frasier's old college friend Alan Cornwall, now a university professor, in the new season.

Grammer reprises the titular role as psychiatrist Dr Frasier Crane, who first appeared in the sitcom Cheers, set in Boston, before landing his own spin-off set in his hometown of Seattle.

In the new series, he has returned to Boston and has "new challenges to face, new relationships to forge and an old dream or two to finally fulfil".

He previously described Lyndhurst as "one of the funniest people" he has worked with.

Streaming network Paramount+ announced on Tuesday that the new show will launch in October.

Often mentioned in the original series, Frasier's son Freddy will be played by British actor Jack Cutmore-Scott, best known for US crime series Deception.

Toks Olagundoye, who starred in the Fatal Attraction series reboot, will play new character Olivia, Alan's colleague and head of the university's psychology department.

The Expanse star Jess Salgueiro is also joining as Freddy's roommate Eve, while Anders Keith plays Frasier's nephew David.

A teaser for the show features a new recording of the original theme song, Tossed Salads & Scrambled Eggs, and a promise that "Frasier has re-entered the building" - with "no more callers" but "all new hang-ups".

Frasier originally ran from 1993 to 2004, and previously starred Jane Leeves as Daphne Moon, David Hyde Pierce as Dr Niles Crane, and Peri Gilpin as Roz Doyle.
