Tonight at 6:30 p.m., AETN and KUAR will host a free preview screening of the new documentary “The Trials of Muhammad Ali,” at the William F. Laman Public Library. From the producers of “Hoop Dreams,” and the Academy Award nominated director Bill Siegel (“The Weather Underground,” “The Road to 9/11”), the film focuses on Ali’s conversion to Islam and the controversy and legal troubles surrounding his refusal to serve in Vietnam (In 1967, he was convicted of draft evasion, sentenced to five years in prison and banned from boxing).The documentary premiered at last year’s Tribeca Film Festival.

A post-screening discussion will be led by Ojima Omar Robinson and Dr. Michael R. Twyman, director of the UALR Institute on Race and Ethnicity.
