In April 1983 an advisory committee of the LAUSD recommended closing eight LAUSD schools, including Bellagio Road School. The committee did not target Fairburn Avenue School in Westwood, as a way of allowing it to preserve its ethnic balance, and so it can take children from Bellagio Road in the event that it closed. In August 1983 the board publicly considered closing Bellagio, which had 240 students at the time. The school's enrollment had been decreasing. In May 1983 the board voted to keep the school open. In February 1984, after the composition of the board had changed, the board voted to close the Bellagio Road School.

Television shows and films have been filmed in Bel Air, or are said to take place in the community. Exterior shots for the Beverly Hillbillies were shot in and around 750 Bel Air Road, built by Lynn Atkinson (and later sold to hotelier Arnold Kirkeby after Atkinson's wife refused to move into a house she thought too ostentatious). After the exterior shooting was completed, the residents of that address forbade any more filming, as passers-by would wander onto the property and ask to see 'Granny'.
