Filmed '91, released '94? It looks like it was made earlier because...

Amy Locane was 19 in 1991, she definitely looks a few years younger than that in the movie, and she looked older in Cry Baby which was released 1990, so Cry Baby may have been filmed in '89. I know people can grow a lot in a short time during their teen years but it still doesn't make sense to me. If I had to guess when Blue Sky was filmed it looks to me, anyway, more like late 80s
