Edited 12 Nov 2015: Watch any movie with an LGBTQQIAAP theme, character, motif, whatever and then report back what think. It's all fair game - anything goes. This is an ongoing, informal, open challenge meant to encourage anyone interested in LGBTQQIAAP cinema to watch more LGBTQQIAAP films. We'd especially love to hear about new or lesser known LGBTQQIAAP films you find - especially ones NOT included in any of the lists below.
If you need some ideas or like to work from a list, consider LGBT List Cross-Reference kindly compiled by forum user @brokenface. It cross references all identified LGBTQQIAAP lists (listed below) and includes movies that appear in three or more lists. Thanks for doing that for us @brokenface!

Let me know if there's anything else you'd like to do with this challenge, okay?
