During an interview with The Wrap at the Sundance Festival, Justin Lin shared that Keanu rescued is latest film.
…We have angels along the way that come and really help us. In this case, I got a call from Keanu Reeves who heard that we were having some problems and he said, ‘Look, I want to help,’ and it was really inspiring.”
Reeves doesn’t have a producer credit on the film — he simply helped Lin by making calls and getting the financing together because he wanted to.
