Description from The Advocate magazine's The Top 175 Essential Films of All Time for LGBT Viewers:

In & Out (1997): The first big blockbuster comedy about coming out, this Frank Oz popcorn flick is famous for the (then-groundbreaking) 10-second kiss between Kevin Kline and Tom Selleck, both big stars at the time. The film is inspired by Tom Hanks's real-life Oscar speech in which he thanked his gay high school drama teacher. In this one, Kline plays the teacher who is outed by a former student at the Oscars, only it's news to him. But something about it inspires him to reevaluate, and it's not just hunky Tom Selleck. Laughs ensue. It's the type of gay movie you can watch with your grandparents. -D.A.M.
