“Let’s do the Time Warp again.” Wellfleet Harbor Actors Theater will host a film series focused on cult musicals, with introductions and post-film discussion moderated by series curator Marc Strauss, an author and professor.

The series will open at 7 p.m. Friday with 1975’s “The Rocky Horror Picture Show,” a horror-movie spoof that involves sex, transvestitism and rock music in a story about a straight couple stranded in an old dark house full of Transylvanians – with actors including Tim Curry and Meatloaf.

The series will continue Nov. 9 with 1980’s “Xanadu,” a remake of a 1947 Rita Hayworth musical (“Down to Earth”) starring Olivia Newton-John as a muse who inspires a young roller-boogie artist, with Gene Kelly and music by Electric Light Orchestra, Cliff Richard and the Tubes. The Nov. 16 choice is “Little Shop of Horrors,” from 1986, a black comedy musical (based on the off-Broadway musical by Howard Ashman and Alan Menken) about a nerdy flower-shop employee who has an unusual, and blood-hungry, new plant.

On Nov. 23: “Hairspray,” the 2007 version starring John Travolta, Christopher Walken and Queen Latifah, based on the Broadway adaptation of John Water’s original 1988 movie about a teenage girl fighting racism through music in 1962 Baltimore. The series will conclude Nov. 30 with last year’s “Baby Driver,” an action-crime film about a music-loving getaway driver, with choreographed action rhythmically synchronized with the soundtrack of rock 'n’ roll and R&B.

Strauss, who recently retired and moved year-round to Wellfleet, is a professor emeritus in theater and dance at the Holland School of Visual and Performing Arts at Southeast Missouri State University. While there, he taught dance and other classes, including the history of the musical, dance history and appreciation, and dance in world cultures. His specialized interests include Broadway and Hollywood musicals, dance criticism, dance on film, aesthetics, George Balanchine, Astaire and Rogers, and Alfred Hitchcock.

Strauss’ books include college texts on dance, “Alfred Hitchcock’s Silent Films,” “Hitchcock’s Objects as Subjects: the Significance of Things on Screen” and, due in 2019, “A Liberal Artist’s Guide to Musicals.”
