On the day the U.S. military will officially lift its ban on gays and lesbians in the military, HBO will screen the new documentary from filmmakers Fenton Bailey and Randy Barbato ("Becoming Chaz," "The Eyes of Tammy Faye") "The Strange History of Don't Ask, Don't Tell." The film will have a sneak preview Monday September 19 at midnight and will air again Tuesday, September 20 at 8PM.

The film follows the history of the bill, from the lead-up to Bill Clinton's signing the policy into law to its repeal earlier this year. The policy has resulted in the discharge of 13,368 active service members.

The film features interviews with Rep. Barney Frank (D-MA), Sen. Joe Lieberman (I-CT), Iraqi war vet and former Rep. Patrick Murphy (D-PA), Lt. Col. Victor Fehrenbach, Col. Margarethe Cammermeyer, and more.
