Reuniting the cast of A Fish Called Wanda, the farcical comedy Fierce Creatures is a comedy train that never slows. Jamie Lee Curtis stars as Wella Weston, a corporate executive who must make the Marwood Zoo profitable again. Her decision to only display fierce animals puts her at odds with the zookeepers who fear losing their beloved animals. Caught in the middle is the Zoo's newly appointed director Rollo Lee (John Cleese) who is at his wits trying to please everyone. Learning the zoo is closing, they are all forced to work together if they wish to save it.
