The $211,586,000.79 that Louisa wants to donate to the United States government in 1964 would be equivalent to more than $2 billion in 2024.

Frank Sinatra was the first choice to play Rod Anderson. When Darryl F. Zanuck balked at his salary demand, Robert Mitchum agreed to play the role at no fee for tax purposes.

Shirley MacLaine is quoted as saying she was happy to work with Edith Head, with a $500,000.00 budget, 72 hairstyles to match the gowns, and $3.5-million gem collection, on-loan from Harry Winston. The value of the gems, adjusted for inflation, would be $23.5 million in 2016.

The set used as Luisa and Pinky Benson's Hollywood mansion was originally used as the home for the characters played by Marilyn Monroe and Dean Martin's in the unfinished 1962 Twentieth Century-Fox film "Something's Got To Give", which was modeled on director George Cukor's private Hollywood home.

When Elizabeth Taylor was still attached to the project (then titled "I Love Louisa"), actors seeking to play her husbands included Frank Sinatra, Burt Lancaster, Kirk Douglas and Tony Curtis--none of whom appeared in the final film.

Continuity

When Larry is demonstrating his "Sonic Palette", he creates a rudimentary painting, though still largely devoid of paint. Just seconds later, as he and Louisa kiss and the machine resumes painting from the captured noises, the painting is almost full, as if it had been active for very much longer (as estimated from the earlier brush stroke activity).

Edgar is heavily covered in mud as a result of Lennie's car, yet a moment later, he is lightly covered.

The position of Louisa's hands and her facial reactions change as Larry's artist friend shoots at the balloons tied to her canvas.

Near the end, Louisa and Stephanson are on a couch which rises high into the air. In a medium shot, there is a white lampshade in the background that is below his shoulder. In a following medium shot, the bottom of the shade is about 8 inches above his shoulder. In the next long shot, the top of the shade is at least a foot below the bottom of the couch, a difference of about 4 feet between shots.

When Louisa first meets Larry in the cab, he's eating a banana, with a bruise on the fruit and the peel. In the next scene, it's a different banana with no bruising.



Factual errors

Anderson flies a Boeing 707, which no pilot would attempt to operate by himself. A co-pilot and an engineer are also needed. Also, he is not wearing a headset.

When Crawley punctures the pipeline with his tractor, the pipeline workers appear almost instantly. Unless they happened to be in the area checking the pipeline, the first indication of the puncture would be a detected pressure drop at a control station, followed by the dispatch of personnel. They might have several miles (or more) to check before they found the leak. There would probably be several hours before it was discovered.

At 27:40, the sign on the store misspells "draperies" as "draperys."



Revealing mistakes

Louisa is clearly hit by one of the robotic paint brushes in the painting sequence with Larry. It occurs when she is walking after him among the animated brushes and the contraption hits her on the head.

At Pinky and Louisa's pool, several bright stage lights are reflected in the sunglasses' lenses of Louisa (while she is seated) and Pinky (after he comes down the stairs).

The flight deck of Anderson's plane is not a Boeing 707, as the exterior shots establish: There is no flight engineer position, and the control yokes appear to be from a Douglas. In addition, there are a number of instruments behind the pilot's position.
