Really happy to see this is getting good reviews. I was going to see it no matter what since GDT is one of my favorite directors, I love the concept, and I'm a big fan of most of the cast.
I wish I could find out if there is some way to know when and where they are doing test screenings. My mom and I got to take part in test screenings for the second two Shrek films at the local theater, and it was a cool experience that I would love to do again. The Shrek thing was actually a surprise because they didn't tell us what movies we were seeing, and I can't remember for sure if they even told us it was test screenings. I think they just gave us invites to a special event happening soon.
