Like in Carpenter's earlier film "Escape From New York," Russell wasn't afraid to improvise and suggest ideas, resulting in a hilarious gag for "Big Trouble in Little China."
In “Little China,” Jack kisses his love interest Gracie. Her bright red lipstick smeared onto Jack's lips and stayed there, as Russell thought it would be a great visual gag.
In the oral history published by EW, Russell said, "[In kissing scenes] how come that big red lipstick is always magically not there when the guy pulls back?"
Russell proposed the idea of leaving it on, and Carpenter agreed. The actor added, "I always admired John for that, because the audience is going to go, 'What the f—?'"
