The film was originally planned to be a short film. The final interview time was extended from six months to six years. The equipment used ranges from the expensive and complicated super-8 camera to the simple iphone. Bender made Raul almost bankrupt to film it. During this period, he invested $80,000 and personally created the soundtrack for the film.

Due to the shortage of production funds, Swedish director malik bendjelloul shot the last 10% of the film on his iphone with the downloadable APP 1.99.

Bender asked Raul to call Simon Chinn, a famous American documentary producer, and told him that he had a story "comparable to a tightrope walker". Finally, after watching some completed movie clips, Zien signed up as the producer of this movie, which not only brought money for shooting, but also improved the popularity of the whole movie.

At the end of 20 1 1, the film was selected as the opening film of Sundance Independent Film Festival in the United States in 20 12.

Malik bendjelloul, the film director, said that the film shot on the iPhone in the final stage was "almost as good as other parts". Chi Hongyu, president of Nacovio, said that he watched the live broadcast of the Oscar ceremony and was very happy with the result.

He said: "The 8mm Vintage camera application is used by many independent musicians for music video shooting, but now it is used by a drama film and an Oscar-winning film. This is an amazing and exciting experience for us. "

The price of the 8 mm old camera app in the Apple App Store remained unchanged on Monday, while the description of the app added information about the Oscar winners. It is understood that after the film came out, a record company has signed a contract with Rodriguez, and he is currently preparing his new album. For the new disc, the low-key and humble Rodriguez said that this is by no means for money.
