Movie people are legendarily liberal and left leaning, particularly when it comes to the environment. “Greenlit” puts their commitment to the test, as eco-friendly young producer and filmmaker Miranda Bailey decides to change her ways after she realizes that Hollywood is Los Angeles No 1 polluter. “Greenlit” follows the production of “The River Why” while she attempts to keep an environmentally friendly set thanks to the supervision of a “green” consultant. What starts off with great enthusiasm, quickly devolves in this insightful and hilarious film, which documents her passionate, yet unintentionally funny efforts to reform a small film crew that simply refuses to digest the concept of environmentalism. Kermit the Frog was right after all: It’s not easy being green!
