The Prytania Theatre is hosting its Arts Week film series Friday through Thursday. The Prytania, the only single-screen theater in Louisiana and the oldest operating cinema in the New Orleans metro area, marked its 100th anniversary in January.

Arts Week films are:

“UPSTAIRS INFERNO”: This documentary examines the 1973 fire at the UpStairs Lounge in New Orleans and the fire’s likewise devastating aftermath. An arson, the fire caused the largest gay mass murder in U.S. history. Despite its historical significance and 32 deaths, the incident is not well known. The crime remains unsolved.

Showing at 3:45 p.m. and 8 p.m. Friday through Thursday.

“THE WOLFPACK”: The Angulo brothers spent their childhood locked in an apartment on the Lower East Side of Manhattan. In their isolation, the brothers learned about the outside world by watching movies. Nicknamed “The Wolfpack,” they re-enacted their favorite films using elaborate homemade props and costumes. After one of them escapes, The Wolfpack has to learn to integrate itself into society without sacrificing their unique bond.

Showing at noon Monday, Tuesday and Thursday and 10 p.m. Friday through Thursday.

LOVE & MERCY”: A moving, albeit unconventional, biopic about Beach Boys leader Brian Wilson, “Love & Mercy” features two eras of his life and two actors in the role of the troubled musical genius. Paul Dano plays Wilson in the 1960s and John Cusack is Wilson in the 1980s. Elizabeth Banks co-stars as the musician’s second wife, Melinda, and Paul Giamatti plays his 24-hour-a-day psychotherapist Dr. Eugene Landy.

Showing at 1:30 p.m. and 5:45 p.m. Friday through Thursday.

Prytania Arts Week tickets are $5.75 for matinees; $11.50 adults evening; $10.50 students evening; and $9.50 seniors and children evening.
