Bruce Willis's performance won a Golden Raspberry Award (Razzie) for "Worst Bruce Willis Performance in a 2021 Movie", a one-off category for Willis's roles in eight films released that calendar year. On March 30, 2022, Willis's family announced his retirement due to a diagnosis of aphasia, a cognitive brain condition. The Razzie committee rescinded the award the next day, saying "If someone's medical condition is a factor in their decision making and/or their performance, we acknowledge that it is not appropriate to give them a Razzie."
Bruce Willis filmed all of his scenes in just 2 days. He is said to have earned $2 million for his work on the film.
In an homage to Star Trek (1966), during the initial battle with the aliens, Dr. Lea Goss states, "I'm a doctor, not a god." Dr. McCoy of the USS Enterprise had many sayings similar to this.
