Playing tomorrow night at the Alamo Drafthouse South Lamar (6:30pm) is In a Dream, a documentary focusing on Isaiah Zagar, a man whose amazing creative vision overlays dysfunction. He's a legendary mosaic muralist, who's managed to cover more of Philadelphia with his murals than teenagers have with graffiti. I'll be there tomorrow even though it also plays twice more. This morning, Zagar and his son (who directed the film) were outside the also legendary Stubb's Barbeque installing a set of his signature murals along the fence that surround the stage. I hope they stay permanently.
