According to IMDbPro, Destination Wedding is still in post-production. We know that there have been a couple of test screening that audiences liked. The film must be closed to being finished as IMDb is showing a release date for The Netherlands of July 5, 2018.
Note: Often reported release dates change at the last minute. I expect both Keanu and Winona Ryder to be actively promoting this film. A release date in the states and elsewhere in July may conflict with the John Wick 3 shoot. That being said, it’s looking like we will see both Replicas and Destination Wedding this year.
