ArcLight Cinemas was an American movie theater chain that operated from 2002 to 2021. It was owned by The Decurion Corporation, which was also the parent company of Pacific Theatres. The ArcLight chain opened in 2002 as a single theater, the ArcLight Hollywood in Hollywood, Los Angeles, and later expanded to eleven locations in California, Massachusetts, Maryland, and Illinois.

The Cinerama Dome is a movie theater located at 6360 Sunset Boulevard in Hollywood, California. Designed to exhibit widescreen Cinerama films, it opened November 7, 1963. The original developer was William R. Forman, founder of Pacific Theatres. The Cinerama Dome continued as a leading first-run theater, most recently as part of the ArcLight Hollywood complex, until it closed temporarily in March 2020 due to the COVID-19 pandemic in California. The ArcLight chain closed permanently in April 2021, with the theater never having reopened. In June 2022, it was announced that there were plans to reopen it and the former ArcLight Hollywood under a new name, Cinerama Hollywood.
