"Once you know the secret, don’t let the cat out of the bag", declares the poster for Argylle, which front-and-centres the family cat belonging to director Matthew Vaughn and his wife Claudia Schiffer (to be fair, the cat does have more screen time than many of its purported stars).
In terms of figurative cats out of bags, the film is so giddy on twists – with a new one coming every few minutes – that when the Big Twist arrives it lands without much impact, especially since it's something of a cliché in the modern spy genre.
