SLGFF 2009 sprints to a close with another weekend of queer screen delights. Today's best bets: Stuck!, the jailhouse-noir dyke comedy starring the mighty Karen Black (4:30 pm at Admiral Theater); Prayers for Bobby, the Lifetime-TV weepie featuring Sigourney Weaver as the unforgiving Christian mom who drives her gay son to suicide, then spends the rest of her life atoning (7 pm at Central Cinema); and One Night Stand Up: Drag Queens, a filmed stage show featuring Jackie Beat, Miss Coco Peru, and Varla Jean Merman (9:30 pm at Cinerama).
