The film, of course, is as much about the appeal of the model as the home. But by using sex, helicopters and shots of a gleaming red Corvette to sell the property, Neo made it quite clear: In this sort of marketing, peddling a fantasy can help close a deal.

Ben Bacal began adding actors to his listing videos in 2014. The Los Angeles-based agent, a former film student who also dabbles in internet companies and has more than $2 billion in sales to his name, is a fixture on the high-priced home circuit in Hollywood. He offers his clients a professionally produced video for every home he agrees to represent, and he estimates that in 40 percent of those cases, he includes actors and a story line.

Some are sweet: A home in Bel Air, which he listed in March 2016 for $48.5 million, shows a brother and sister channeling their best Ferris Bueller impressions, faking sickness in their custom bedrooms before dashing out to their backyard infinity pool with skyline views after their parents head off to work. (The home sold for $39 million in December 2016.)

Others are more slapstick, like the film for a home on Rising Glen Road in Los Angeles (the house where the actress Brittany Murphy died), in which an adorable corgi named Sherlock Bones inherits the mansion listed for $18.5 million and heads there to live his best canine life. (That home sold in 2017 for $14.5 million.)

In all of Mr. Bacal’s videos, plots are thin but visuals, and humor, are laid on thick. That’s intentional, he says.

“Instead of telling a long dramatic story, I like to pull characters through the house and do something that makes it voyeuristic, where you can see the property. Focusing too much on story takes away from the home,” he said in a phone call from Mykonos, Greece, where he was on vacation. “I’m not Quentin Tarantino.”
