Crist's office sent a letter dated June 30 and bearing the governor's signature that thanked John Ubele for providing the governor with a DVD of "Jud Suss." The Nazi-produced film is recognized as one of history's most incendiary.

In closing a brief thank-you note, Crist praised Ubele's thoughtfulness and generosity and said he would be delighted to share the DVD with the people of Florida.

"I was surprised considering the stigma that has been associated with the film," Ubele said Friday in an exchange of e-mails with The Associated Press. "I was even more surprised when I looked at the signature because from what I can tell it looks real."

Ubele said the signature appeared to be signed by a marker.

The governor's office, however, said it was an embarrassing mistake.

"We are NOT sharing the DVD with the people of Florida," said Sterling Ivey, the governor's press secretary. "The governor does not support this view. The letter was sent out prior to us reviewing the DVD that was sent."

The 1940 film was produced by the Nazi propaganda arm and was a great success in Germany and abroad, although it was banned in Sweden in 1941 and has never been shown in that country.

Within the Third Reich, "Jud Suss" was the No. 1 film of the 1939-1940 season when it was seen by more than 20 million people. Anti-Jewish violence was reported after its projection only in Marseille, France.

Ubele, who ran unsuccessfully for the state Legislature, is the operations manager of a group called the Nationalist Coalition that promotes "white activism."

On its Web site, the organization says it is working to create the relationships to lay a foundation for the White community necessary to "do whatever is necessary to achieve white living space and to keep it White."
