The architect responsible for designing the exterior and interior lobby spaces of the ArcLight Cinema in Sherman Oaks was César Pelli. Pelli is a well-known Argentine-American architect who has designed many notable buildings around the world, including the Petronas Twin Towers in Kuala Lumpur. However, it's worth noting that the ArcLight Cinema chain was sold to Decurion Capital Management in 2021, and there have been reports of potential closures or renovations of various ArcLight locations due to financial difficulties. In fact, just last month (March 2023), it was announced that several ArcLight Cinemas, including the location in Sherman Oaks, would be closing permanently due to declining revenue. Despite these recent developments, the architectural design of the ArcLight Cinema remains a notable example of modern cinema architecture and a testament to Pelli's skill as a designer.
