No one should ever need an excuse to watch Serenity, the film adaptation of Joss Whedon’s brilliant, too-short-lived space western, Firefly. (Bonus: it’s screening on the Whe-dog’s birthday.) But Can’t Stop the Serenity, tonight at the Coolidge Corner Theatre, offers fans a chance for some Mal-esque heroics, as proceeds go towards women’s rights group Equality Now and your local New England Browncoats will be collecting food for the homeless sanctuary Rosie’s Place. Yes, donating means you can officially justify wearing a duster. Chanting “I’m a leaf on the wind” on the bus?
That’s all you.
