Trivia

In the restaurant scene, Oliver the vet (Ed Skrein) says he lost track of time watching Game of Thrones. Ed Skrein played Daario Naharis for 3 episodes of Game of Thrones (before the character was recast.)

Beattie Edmondson is the real life daughter of actor/comedian Jennifer Saunders (Absolutely Fabulous, French & Saunders, Muppet Treasure Island) and actor/comedian Adrian Edmondson (Bottom, The Young Ones, Star Wars Episode VIII: The Last Jedi). Saunders appears in the film in a supporting role.

Though the majority of Patrick's close-up scenes were acted by canine actor Harvey, 17 different pugs were used to portray the character throughout the film, not all of them male! At various points the role was played by pugs Foggy, Wesley, Edie, Pearl, Truly, Marina, Glenda, Barry, Howerd, Wally, Nora, Blamire, Entwistle and twins Compo & Clegg! To ensure consistency in the sound of Patrick's 'voice', vocal styling was provided by an uncredited Stephen Lewis.

The ship Sarah & Patrick live on was in the middle of a full-restoration when it was spotted by location scouts. In April 2017 the production team took over, restoring the interior and stripping her brand new white and grey exterior paint-job back to look like a wreck again, so the vessel could be restored as an ongoing plot point in the film. After filming completed she retained her new blue look, including Patrick's paw prints.

Trailblazing British comedy Producer/Director Mandie Fletcher (Blackadder, Only Fools & Horses, Open All Hours, Not The Nine O'Clock News, Desmond's, Brush Strokes, Butterflies) is a close friend of Jennifer Saunders, having directed her in many television shows since the 1980s. Projects she has directed involving Saunders include Absolutely Fabulous, Absolutely Fabulous The Movie and the revival of PG Wodehouse's Blandings,

Fletcher also directed Saunders' comedy partner Dawn French in Roger & Val Have Just Got In.
