An outdoor triple feature from Baltimore's connoisseur of bad taste, John Waters, is on tap tonight at Middlebranch Park, 3301 Waterview Ave. Part of the Alamo Drafthouse Cinema's Rolling Roadshow Tour, tonight's fest of Waters' best includes the nonmusical version of Hairspray (1988); Polyester (1981), an ode to life in suburbia starring Divine and Tab Hunter; and Desperate Living (1977), all about life in a garbage dump-cum-homeless shelter known as Mortville. As if that lineup isn't enough, the first 250 people to show up will get a free limited-edition Odorama card, essential for experiencing Polyester in all its glory. Admission is free, unless you want to purchase a $30 VIP ticket, with which you get special seating, a commemorative print and an invitation to the after-party. Information: rollingroadshow.com

Salute to film noir
The Charles Theatre's summer-long salute to film noir continues this weekend with the movie that defined the genre, Billy Wilder's 1944 Double Indemnity. Fred MacMurray stars as Walter Neff, a life-insurance salesman who's honest enough, until he falls under the spell of hot-to-trot Phyllis Dietrichson (Barbara Stanwyck), who insists the two of them could have such a great life together, if only they could do something about her husband. Showtime is noon tomorrow, with encores set for 7 p.m. Monday and 9 p.m. Thursday. Tickets are $6 tomorrow, $8 other times. Information: 410-727-FILM or thecharles.com.

Directed by Daniel Petrie, the film - an adaptation of Lorraine Hansberry's award-winning stage play - stars Poitier as Walter Lee Younger, whose mother's plans to move the family out of its cramped city apartment to the suburbs are hindered by racism and pent-up frustration. The series concludes next week with 1967's To Sir, With Love. Showtime is 8:30 p.m. at the Clifton Park Band Shell, off of St. Lo Drive. Information: 410-366-2222 or clifton cinema.org.
