“Bob Peak: Creating the Modern Movie Poster” Like the films they advertise, movie posters can be dull, formulaic, even obtuse. But as this exhibition demonstrates, some bills manage to be more — intriguing hooks, elegant examples of succinct storytelling, works of art in their own right. This collection of original paintings and final one-sheet posters by Peak features such memorable films as “Superman,” “Apocalypse Now” and “The Spy Who Loved Me.” Fourth Floor Gallery, Academy of Motion Picture Arts and Sciences, 8949 Wilshire Blvd., Beverly Hills. Noon-6 p.m. Sat. and Sun. Free. (310) 247-3000. https://www.oscars.org

POP MUSIC

Ghost of a Saber Tooth Tiger It’s apropos that Sean Lennon and Charlotte Kemp Muhl would pick Pappy & Harriet’s as the place to bring their folk project. Their music is haunted by all sorts of times and places past — Syd Barrett’s sun-scarred psych and pastoral English folk; a lyrical world of hope glimmering in corners of apocalypse; Lennon’s uncannily familiar vocal lilt and way with unexpected guitar runs. Pappy & Harriet’s, 53688 Pioneertown Road, Pioneertown. 8 p.m. $15. pappyandharriets.com. Also at the Troubadour, 9081 Santa Monica Blvd., West Hollywood. 8 p.m. Sun. $18. troubadour.com

BOOKS

Riverside Dickens Festival We’re not sure that the sunny hamlet of Riverside has nearly enough street urchins running around in fingerless mittens; nevertheless, it will host the annual literary festival celebrating Dickens and his most sustaining creations, including “Oliver Twist” and “David Copperfield.” Activities and entertainment will include costumed characters, an ale house, plays, dancing, fashion shows and Victorian tomfoolery. It will surely be the best of times but, we hope, not the worst of times. Riverside Dickens Festival at the Riverside Convention Center, 3443 Orange St. 9:45 a.m.-5 p.m. Sat.-Sun. dickensfest.com

MOVIES

“Repo Chick” More than a quarter-century after the release of the Emilio Estevez-starring “Repo Man,” the cult classic’s director, Alex Cox, reprises familiar themes with “Repo Chick.” The Downtown Independent hosts a rooftop premiere party to celebrate the release of Cox’s return to the realm of repo people, this time chronicling the valiant efforts of a spoiled brat turned repo girl named Pixxi de la Chase who stumbles on and must thwart a terrorist plot to destroy downtown Los Angeles. Downtown Independent, 251 S. Main St., L.A. 7 p.m. $10. https://www.downtownindependent.com
