Jane Fonda purchased the rights to the play specifically for her father,
Henry Fonda, to play the cantankerous Norman Thayer. The father-daughter rift depicted on-screen closely paralleled the real-life relationship between the two Fondas. The producers originally offered the role of Norman Thayer to
James Stewart, but he declined.
Anthony Michael Hall auditioned for the role of Billy Ray Jr., which eventually went to Doug McKeon. Screenwriter Thompson spent his summers along the shores of
Great Pond, located in
Belgrade, Maine, but the film was made on
Squam Lake in
Holderness, New Hampshire. The house used in the film was leased from a New York physician and was modified significantly for the shoot: an entire second floor was added as a balcony over the main living area at the request of the production designer. After the shoot, the production company was contractually obligated to return the house to its original state, but the owner liked the renovations so much that he elected to keep the house that way and asked the crew not to dismantle the second story. A gazebo and a small boathouse were also relocated during the shoot. The Thayer IV was the name of the boat used in the film. There were three Thayer IV's used in the movie, including one replica used for the crash scene. One was a 1950 Chris-Craft Sportsman (U22-1460), bought by a family in 1982 from marine coordinator Pat Curtin. The other boat, also a
Chris-Craft Sportsman (U22-1802), was sold in 1983 by Curtin. It was the boat Fonda and Hepburn used for their excursions on Golden Pond. At the same time, the buyer of U22-1802 also purchased the replica used in the crash scene. Although the Chris-Craft Sportsman was the main boat used in the movie, the script called for the Thayer IV, a
mail boat, a canoe and a replica of the Thayer IV. These were provided by Patrick Curtin of Eastern Classics, a boatyard in
Laconia, New Hampshire, specializing in the restoration of
mahogany speedboats. Following
World War II, the Sportsman model reappeared as a direct descendant of its 1937 predecessors. The popular model stayed in the Chris-Craft lineup until 1960. The use of a 1950 Sportsman model as the Thayer IV in
On Golden Pond did much to generate interest in antique and classic boats. Despite their many common acquaintances and long careers in show business, Henry Fonda and Katharine Hepburn not only had never worked together, but had never met until working on the film. On the first day of shooting, Hepburn presented Fonda with her longtime companion
Spencer Tracy's "lucky" hat, which Fonda wore in the film. Hepburn, who was 74 at the time of filming, performed all her own stunts, including a dive into the pond. The scene in which Norman and step-grandson Billy run their boat into the rocks was filmed repeatedly. The vintage 1951 mahogany
Chris-Craft boat, used strictly for the crash scene, was so sturdy that it kept bouncing off the rocks without any damage. The crew had to modify the boat so it would break away in the wreck. The water level in
Squam Lake was so low during the summer of production that Fonda and Doug McKeon could have stood during the scene in which they were supposedly clinging to the rocks for fear of drowning. The September water was barely knee-deep, but it was cold enough that the pair had to wear wetsuits under their clothes. Hepburn, on the other hand, dove into the water without the aid of the wetsuit because she wanted the scene to keep its authenticity. Some of the scenes in which Billy takes the boat on his own were filmed on nearby
Lake Winnipesaukee. While filming the scene in which Fonda and Hepburn are watching the
loons on the lake, the speedboat that sped by and disturbed them was so forceful it overturned their canoe in one take. Fonda was immediately taken out of the water and wrapped up in blankets, as his health was fragile by then. The town of
Holderness, New Hampshire, offers boat tours of Squam Lake and the filming locations in the movie. There is also a restaurant called "Walter's Basin", which is named after the trout called "Walter" that Billy catches with Norman. For filming, "Walter" was brought from a trout pond at the nearby
Castle in the Clouds estate. He was released into Squam Lake after his capture. Leftover footage of Fonda and Hepburn driving through the New Hampshire countryside, as seen in the opening credits, was later used for the opening of the
CBS television sitcom
Newhart. The
studio behind the film was
ITC Entertainment, the British company presided over (until late 1981) by
Lord Grade, the television and film
mogul. It was Grade who largely raised the financing for the film. ==Reception==
