FILM A Diamond in the Rough The next flick in Maryland Hall's Monthly Independent Film Series is one we've told you about here before, which means it's a second chance to catch "Black Diamonds: Mountaintop Removal & the Fight for Coalfield Justice." "Diamonds," made by Baltimore-based filmmaker Catherine Pancake, intrigued movie critic Ann Hornaday with its look at the coal mining industry in West Virginia and the poor Appalachian crusaders who are fighting back. It'll screen Thursday, and afterward, Pancake will be on hand for a chat. $10; $6 for students, seniors and members. 7:30 p.m. Maryland Hall for the Creative Arts, 801 Chase St., Annapolis. 410-280-5640.
