I adored Jenny Agutter's wonderful performance as Hedvig. She was so perfectly natural and endearing--totally believable. I wanted to adopt her.
I thought Denholm Elliott's presentation was subtle and flawless, and Rosemary Leach was wonderful in her perfectly understated delivery of Gina's character. Derek Godfrey was ideal for Gregers.
I did have trouble catching some of the dialog, maybe because of the British accents. I loved the production enough to read Ibsen's play, and caught a lot of it that way. The elder Mr. Ekdal's mumblings were great to read (he mumbled on purpose and injected a lot of insight and humor).
The parts of the script that were left out of the TV play added to my understanding of the characters, which I firmly believe were honestly portrayed by each of the actors.
I have the Ibsen Collection, and if anything happened to the disc with The Wild Duck on it, I would gladly buy the whole collection again just for this play.
