 The original script takes place in a single room in a single day, but the Mercer/Losey version is much wider ranging.Much of the expository dialogue of Act I is converted into an extensive prologue.Events that are only discussed by the actors in the Ibsen play – such as the early friendship of Nora and Kristine, the romance and breakup of Kristine and Krogstad, the life-threatening illness of Torvald, and the death of Nora's father – are all fleshed out in full separate scenes at the start of the film.
