The Champion is notable for being the first film for which a foreign-language version (in English) was created in which the actors' facial movements are modified so that they appear to be speaking that language. The work was done using a technology similar to deepfake, proprietary to the Tel Aviv-based tech startup Adapt Entertainment, which bought the English-language distribution rights for The Champion so that it could serve as a proof of concept for its technology.[8]
The film was announced in 2019.[3] The shooting finished in January 2020.[2] The movie was initially scheduled for release for 16 October 2020[9][10] but has been delayed with the new release date given as March 2021.[11] The delay was likely caused by the impact of the COVID-19 pandemic on the Polish cinemas.[11]
The Tel Aviv-based startup Adapt Entertainment is based around proprietary machine learning process, named Plato, that uses AI to modify actors' faces within film and television shows in order to make it appear that those actors are speaking another language, as a substitute for dubbing.[12] The software is similar to but distinct from deepfake technology. The company bought the English-language distribution rights to The Champion at the 2021 Cannes Film Festival for $100,000, after the film had seen financial success in Poland, as a proof of concept for its process. They then hired much of the film's original cast to be filmed at a studio speaking the film's dialogue in English, and used the resulting audio, as well as a combination of the old and new footage as training material, to infer the characters' facial movements to match the new dialogue.[13][8][14]
Director Barczewski was supportive of the new version, saying he had wanted to additionally film The Champion in English but could not afford to do it.[14]
