The H-4 Hercules, aka, "The Spruce Goose," actually flew its one and only flight on November 2, 1947, well before the events of the film.

Factual errors

The Mabrey,s as Baptists, said a commonly used Catholic grace before a meal. In that period of the 1950's, no Baptist would be caught dead in saying a Catholic anything.

Errors in geography

When Frank first drives Marla and her mom, they travel east on Hollywood Boulevard, passing the Egyptian Theatre on their right. A few seconds later, the Chinese Theatre goes past on their left. They should have passed the Chinese Theatre first.

Factual errors

The takeoff of the Lockheed Constellation was inconsistent with flight characteristics of the Connie, or other propliners of the day. The plane took off, rotated, and climbed at a 30 degree angle. This was not an F-14 jet fighter, folks. That airplane's rate of climb was about 1/4 that of a jetliner, whose power to weight ratio was much higher.

Anachronisms

Throughout the 1958 scenes, Frank is driving a 1961 Chrysler. Hughes wasn't that rich.

Factual errors

The movie begins with a "1964" dateline and later has a "five years before" card on screen.

By 1959 they had already done so and in fact played the Chicago White Sox in the World Series that year.

Plot holes

Howard Hughes was married to Jean Peters from 1957-1971 so was not single and needing a wife to keep him out of the loony bin as purported in the story line.

Anachronisms

Although supposedly set in 1958, Hughes' is shown crashing the XF-11 prototype aircraft, which actually happened over a decade earlier, on July 7, 1946.

Anachronisms

Although it's 1958, the film shows the "5 Star" street lights lining Hollywood Blvd as Frank drives. The "5 Star" lights didn't go in until 1960 when the Walk of Fame was constructed.

Miscellaneous

In one scene, Howard and Harlan discuss the fact that Marla is the only RKO contract girl with the initials MM. Later in the film, however, we learned that Mamie's last name also begins with the letter M.

Character error

In a conversation with Marla Howard refers to "a couple of limeys" who worked out DNA. Watson and Crick did their work in England, but Watson is American.
