The Strand Theatre, 345 Main St., is offering a free screening of “Gosford Park” (2001, UK/USA/Italy) to its members Tuesday, Aug. 1, at 7 p.m. Current Strand Theatre members, as well as anyone who becomes a member prior to the screening, are invited to attend. Memberships will be available to purchase at the door.

The theater, which has been designated a National Historic Landmark by the National Trust for Historic Preservation, became a nonprofit in January 2014 and is now operated by Friends of the Strand Theatre. Memberships, as well as grants, sponsorships and fundraising efforts, help pay the operating expenses for the wide range of cultural and educational programming the theater offers to the community.

In “Gosford Park,” an intelligent murder mystery set in the early 1930s, maverick American filmmaker Robert Altman took a witty and absorbing look at the foibles of the British class system. A pair of wealthy British socialites has invited a variety of friends, relatives and acquaintances to their mansion in the country for a weekend of hunting and relaxation. The servants are required to display a high level of decorum and be passive observers, although the gossip travels fast once they retire downstairs. When the lord of the manor turns up dead, everyone is ordered to stay at the mansion while the police investigate the killing. The film stars Maggie Smith, Michael Gambon, Kristin Scott Thomas, Helen Mirren, Alan Bates, Ryan Phillipe and more.

No regular admission tickets will be available for this show. Strand Members should present their membership cards at the door for admission, plus free small popcorn and a fountain drink. For more information about the Strand Membership program, call 701-5053 or email jripley@rocklandstrand.com.
