By the middle of the decade John Carpenter had a swag of genre hits and cult titles up his sleeve and took to this when its writers gave him the gig. It had begun as a western but then had been modernised until it was set in present day San Francisco among the Chinese community and the netherworld below it, featuring martial arts and magic. There's not only a lot of Hong Kong style wirework but the technique itself is mentioned in dialogue.
There is little point in describing the plot of this one. The action takes over, allowing for some character development, and doesn't stop until the end brings the inevitable pairings and scissions before the credits roll. That makes it sound shallow but this movie's glee at throwing out tough situation after tough situation will keep the shortest attention span occupied for its whole runtime.
The cast does their best to stretch their cartoony characters to fit the colour and art direction. Dennis Dun adds more depth here than to his gawky goof in Prince of Darkness two years later, and makes a lot out of his action hero by accident. Kurt Russell surely has the most fun out of his boastful and bumbling self-appointed action king role, getting inadvertently injured more than anyone else and being wrong in most of the decisive decisions he makes. Standing as he did beside the Schwazeneggers and Stallones of the era, he presents something like what an action man might be like in real life, all one liners and incompetence. And then there is the young Kim Cattrall, the weak link who can't quite resolve the jarring mix of Marilyn Monroe and Kathleen Turner and ends up short of her character's comedy and decisiveness. But it is James Hong who steals everything as Lo Pan the sorcerer, an evil ancient man here and a feeble old man by the light of day, whose lust for immortality is grounded in more fleshly lusts that might have reminded the likes of Kim Cattrall of more than one casting sessions when starting out.
In a few ways, Big Trouble is like a funny presage of the more serious idea of Prince of Darkness with a pair of forces drawing together for an apocalypse. More pertinently, if you were to watch all of Carpenter's movies back to back from Dark Star to They Live, Big Trouble would be a welcome action comedy between the solemnity of Starman and the sci-fi doom of Prince of Darkness. If it is neglected in his canon even by fans it's surely not because of underperforming at the box office (the mighty Thing also had that honour) but more from the inconvenience of its jutting out. Christine is better recalled even if it is less Carpenter than Stephen King. Perhaps fans just wanted more Snake Plissken or MacReady from Kurt Russell or found the refusal to overly stereotype the Chinese community against the times. Nevertheless, it's one of Carpenter's most persistently fun from all his works and does its job with every viewing.
Viewing notes: I watched the Disney+ presentation at Blu-Ray resolution and sound which is superb and fitting. You can still buy a well polished DVD at a low price point.
