Many have heard about the shocking moment when Tourette's activist John Davidson hurled an involuntary racial slur at Michael B. Jordan and Delroy Lindo at the BAFTAs. It's hard to keep that sad moment out of one's head while watching “I Swear.” Kirk Jones' film about Davidson's life is now releasing in the U.S. Associated Press critic Jocelyn Noveck writes in her review that the movie owes its success to superb acting from Robert Aramayo. It's a moving tale encumbered by a desire to present a linear path toward acceptance for Davidson and others with Tourette's. We know from the BAFTA incident just how hard that will be.
