Here's a neat idea: Steven Soderbergh has released Command Z, a series of interconnected shorts about time travelling to fight climate change. To watch, you pay 8 bucks, all of which goes to support Children's Aid and the Boston University Center for Antiracist Research.
I've just finished the series, and while it's not peak Soderbergh, its heart is in the right place and there are some good laughs and thoughtful commentary on our present catastrophe. Plus, giving 8 bucks to charity to see what amounts to a feature-length film is a way better deal than most moviegoing opportunities. Three out of five stars, with a bonus half-star for trying to change the world for the better.
