We've asked Amazon for comment. The Prime Video operator's involvement would make sense when dj2 has a "first look" deal with Amazon, as do the movie's executive producers (and writers) Pat Casey and Josh Miller. It Takes Two developer Hazelight Studios' Josef Fares and Oskar Wolontis will also executive produce.
Update 4/21 12:25PM ET: Amazon has confirmed the production details, although it's still not clear if Johnson will act in the movie.
