'Hedvig' is the only character whose name remained exactly the same from the film's base text 'The Wild Duck'.
Peterson's name also remained the same, except for a spelling change.
The film was directed by Simon Stone, who also directed a live theatre production of 'The Wild Duck', Henrik Ibsen's play which is the basis for this adaptation. Ewen Leslie (who plays Oliver) was in the original stage production as Hjalmar (the character on whom Oliver is based).
Second of two Australian cinema movie filmed adaptations of Henrik Ibsen's "The Wild Duck" stage play. The first was The Wild Duck (1983), which was updated to Tasmania in 1913, whilst the the second would be The Daughter (2015), where the setting was updated to modern contemporary times.
Steve Rodgers made a brief appearance in this film as the Head Master. This appearance is a small cameo, as he also appeared in a stage production of 'The Wild Duck' at the Perth Festival in 2016, as 'Hjalmar'. He was replacing Ewen Leslie who plays 'Oliver' in the film.
