The title of this Halifax-based HBO and BBC drama comes from a slur from the time period. "Gentleman" refers to protagonist Anne Lister's more masculine behavior such as wearing dark and black clothing and her knowledge of subjects not usually studied by women at the time. "Jack" was a term used then for lesbians.

All Creatures Great and Small TV show
Alf Wight (the real James Herriot) initially stipulated that all the incidents in the TV series had to be closely based on those in his books. By the end of season three, all of Wight's books had been televised, and it was thought that the series would have to end.
