Macquarie University marketing professor Scott Koslow said that with these videos “you might actually get attention that you couldn’t get otherwise” and “a little bit of confusion might just be a decent price to pay to get people to look at the screen”.

Whether that attention translates to retention is a different question, though. Some airline personnel have attributed the successful evacuation of a Japan Airlines plane that collided with another aircraft earlier this year to the airline’s short and simple safety video.

The little research that exists on the topic suggests the airlines’ Hollywood glow-up may have mixed results.

One 2015 study, with 45 participants, suggests that once a viewer is watching a safety video, a humorous video is better at holding attention than a video featuring a celebrity or a standard video.

Another study from the same year, with 82 participants, found that while safety briefings that are funny or use movie themes positively affect participant’s moods, “there was a trade-off between entertainment and education” and “the greater the entertainment value, the poorer the retention of key safety messages”.

University of New South Wales professor Brett Molesworth, an author on the papers, said the research is clear that any overlap or confusion of the key safety message with entertainment or humour undermined the safety message.

Molesworth said we can only process so much information at a time, and when we encounter something entertaining or funny “it often consumes all of our working memory capacity” and airlines need to “divorce those funny bits or the entertaining bits from the key safety messages”.

Experts say it does not help that these videos sometimes avoid even showing the aircraft. In the British Airways video, seat belts are donned on horseback and the plane exits are explained in a ballroom, while in an Air France safety video, the exit sign is transformed into an outfit worn on a catwalk at a fashion show.

Griffith University lecturer Xiaoyu Wu, who studies aviation and safety practices, said these videos might “attract your attention because they put fake seats in, I don’t know, the jungle,” but they don’t always do a good job of showing the actual safety features of the aircraft. Such videos can miss what’s important, he said, stressing that “if it’s really working, it’s preparing people” in case of an emergency.

At least one airline has made a public point of adopting that perspective. Earlier this month, Emirates released a “no-nonsense” safety video that received praise from several aviation bloggers.

“We do not have dancers breaking into song, characters from movies or celebrities trying to be funny I’m afraid,” one flight attendant says. Another says that while entertainment will be available later: “Safety always comes first.”
