Vincent Gagliostro’s After Louie (B) is ostensibly a “May-September romance” between Alan Cumming as an artist and Zachary Booth as his muse. Through the lens of an engrossing intergenerational relationship, the film spotlights attitudes about the AIDS crisis reflected through those tethered to the heights of its tragedy and those buoyed by a renewed and sometimes more casual outlook on dealing with the disease. The film centers on Cumming’s character getting out of his own head as he clings desperately to the crusades he once championed. His young companion challenges many of his mores and expectations. Both men in the center of the film give sage performances. Don’t let Booth’s matinee idol looks eclipse what a well modulated performance he offers. Some subplots are better developed than others, with a sequence involving some creative painting as a highlight. Character driven with moments of poignancy, it’s a thinking person’s film with some imaginative flourishes.
