A U.S. soldier who defected to North Korea more than 40 years ago while stationed in South Korea will be introduced to the American public for the first time.

Private First Class James Dresnok is the last such American soldier remaining in the communist state.

U.S. television network CBS says it will air on Sunday part of an interview with Dresnok taken from a documentary submitted to the Sundance Film Festival, which opens the same day in Park City, Utah.

The 66-year-old said in the interview that his life in North Korea is very comfortable and he wouldn't leave even if he were paid billions of dollars.

Dresnok crossed the inter-Korean border and defected to the North in August 1962. He is known to have become a member of the North Korean Workers' Party and has appeared in propaganda films.

British director Daniel Gordon made the documentary film "Crossing the Line," on the lives of U.S. servicemen who defected to North Korea as part of a trilogy on the communist country. The film premiered in last year's Pusan International Film Festival in South Korea.
