Not going to post spoilers myself but if you want to find them go to google and search for Ghostbusters Afterlife leaks. after searching click the "tools" option. You'll be given two options: "any time" and "all results" Click the "any time" option and it will give you options to limit how far back you search. Click the option "Past week" That should help you find them.Now that's odd the 1st link I get is someone saying "at a test screening last week".
I have severe doubts any test screenings for any movies are happening right now.
