On Location Vacations has reported that filming took place on Kent Avenue and Browadway in Brooklyn on Wednesday, November 26. Someone left a comment on the thread that said they will be filming on Staten Island on Monday, December 1 and also that Keanu’s part wrapped yesterday (Nov 26). It is not clear if the commenter’s info is credible but I reckon we will know soon enough.
