The tool called Shapeshifter was used in the HBO series, Righteous Gemstones, to de-age John Goodman.
Gradient Effects used their new tool to de-age John Goodman in the fifth episode of Righteous Gemstones. But it's worth mentioning that the tool is a different approach and the technology has been developing for years and was already used for different purposes.
Eli Gemstone is one of the main characters of the show. The HBO describes him as the larger-than-life patriarch of the family, who has built an evangelist empire with his wife and is afraid that their three kids can get lost after his wife's death.
The fifth episode of the show has a flashback, where his life is still alive, and the empire is only growing. In order to make the whole episode look realistic, John Goodman had to be de-aged.
