Lite trivia om filmen:
- The brown Fedora worn by Henry Fonda belonged to Spencer Tracy and was given to Henry Fonda by Katharine Hepburn on the first day on the set. Henry Fonda, overwhelmed with the gesture, painted a still life watercolour of the three hats he wore in the film and gave the original to Katharine Hepburn as a gift. He had 200 lithographs made of the painting and sent one to every person who worked on the film. Each copy was numbered and personally signed by Henry Fonda thanking each individual person by name.
- Katharine Hepburn won her 4th Best Actress Oscar, which to date (1999) makes her the all-time record holder for that category.
- Henry Fonda won the Oscar for Best Actor in a Leading Role for his role as Norman Thayer Jr. At 76, he was the oldest actor to win this Oscar.
- Jane Fonda claims that the scene between Chelsea and Norman (Henry Fonda) where she tells him she wants to be his friend mirrored the real-life relationship between father and daughter. During one take when the younger Fonda unexpectedly grabbed her father's hand, Henry Fonda started to cry and ducked his head away from the camera, embarrassed by his tears. The take appears in the final film.
- The Purgatory Cove scene was shot in late September. To keep warm in the cold water both Doug McKeon and Henry Fonda had to wear wetsuits under their clothes. Katharine Hepburn was supposed to have a stunt double perform her "dive-in" scene for her, but instead she insisted on doing it herself. She dove into the frigid water without a wetsuit.
- On June 29, 2003, Katherine Hepburn died of natural causes at Fenwick, the Hepburn family home in Old Saybrook, Connecticut. She was 96 years old, and was buried in Cedar Hill Cemetery, Hartford, Connecticut. In honor of her extensive theater work, the lights of Broadway were dimmed for an hour.
