One of the first films to show the use of a car mobile telephone when Peter calls Dr. Cook, who is on his way to La Jolla. Two of the first car mobile phone systems were established in Los Angeles and San Diego in 1947.
Scenes for this film were shot at the lavish Marion Davies Beach House in Santa Monica, built for $7 million in 1927. It had been converted to a hotel in 1947. It closed in 1956 and the main house was demolished. The remaining structures and land were sold to the state of California in 1959. It has been open to the public as the Annenberg Community Beach house since 2009. Only the guest house and the pool remain of the original estate.
The $2 million inheritance would equal about $24.5 million in 2024. The film also uses the correct exchange rate at the time i.e. $28 million Argentine pesos equaling $2 million USD.
Fred MacMurray's return to Santa Monica's Ocean House for a scene in what was being filmed under the working title of "The Golden Goose" brought back a sharp memory, according to the "In Hollywood" column by Erskine Johnson, distributed by NEA. His last visit there was in 1929 - as a saxophone player in an orchestra hired by Marion Davies for a big movie party.
