Who made this distorted movie? The Hauptmann family?

The film is a disgraceful patchwork of downright lies and distortions. Hauptmann was as guilty as sin. The following is taken mainly from http://jimfisher.edinboro.edu/lindbergh/a1988_2.html , an excellent summation of the Lindsbergh case.

Hauptmann is connected to the kidnap ladder in the following ways:

Rail 16 of the ladder had once been a floor plank in the attic of his house. It would have been impossible for the police or the prosecution to have fabricated this evidence. It was later determined, however, that people working for Governor Hoffman had tampered with the floor joist in Hauptmann’s attic in an effort to discredit this evidence.
The kidnap ladder contained marks made by some of Hauptmann's carpenter tools.
Nails found in Hauptmann's garage were made at the same place and time as those in the kidnap ladder.
A piece of the ladder was traced to a store in Hauptmann's neighborhood.

Hauptmann didn't earn a wage from April 1932 (the month the ransom was paid) until his arrest in September, 1934. During this period, amid the Great Depression, he had purchased new furniture, several guns, expensive clothes, and had sent his wife to Germany. When arrested, he was wearing a homemade suit of fine material. By his own admission, he had invested $15,000 in the stock market. He had also alarmed his garage.

The film has the police ordering him to misspell words. What it doesn't tell you, for obvious reasons, is that those same misspellings turned up in Hauptmann's notebooks and other of his writings unrelated to the case some of them from many years earlier. Another unbelievable distortion.

In Germany, Hauptmann had served five years in prison for burglary and robbery. He also had a record of escape, and had fled to America to avoid being sent back to prison. His criminal record is glossed over by those who support him.

It's absolutely astonishing that some people continue to think he was innocent. But then people will always favor a far-fetched and elaborate conspiracy to the plain old truth.

The movie needs a disclaimer at the beginning. "We made most of this crap up purely for the purposes of entertainment."

Here's how the website linked above sums up, and it's absolutely true.

Today, the Lindbergh phenomena is a giant hoax perpetrated by people who are taking advantage of an uninformed and cynical public. Notwithstanding all of the books, TV programs, and legal suits, Hauptmann is as guilty today as he was in 1932 when he kidnapped and killed the son of Mr. and Mrs. Charles Lindbergh.
