Family also plays a big role in Johnson's upcoming action romp Skyscraper. In the film, Johnson stars as Will Sawyer, a former FBI Hostage Rescue specialist who lives with his family in the world's tallest skyscraper in Hong Kong, and serves as its chief of security.
Sawyer's world comes tumbling down when the building is attacked by terrorists, which results in a massive fire, leaving his family trapped in the blazing tower and making him the only one who can save the people he loves and everyone else who lives in the giant deathtrap.
While chatting with ET, Johnson was joined by the film's writer-director, Rawson Marshall Thurber, with whom the star previously collaborated on the 2016 action comedy, Central Intelligence.
"Skyscraper's a really fun action movie. It's suspenseful if you're afraid of heights [and] it's a pretty intense experience… But it really is about family and it's about you know, what would you do if your family was in trouble? How far would you go?" Thurber told ET. "So this movie has a lot of heart in it and it's centered on family."
According to Johnson, that aspect played a big role in his excitement for joining the project, along with the fact that the whole movie is a loving homage to the exciting action-packed disaster flicks they loved growing up.
"The inspiration comes from movies that I, we both, loved as a kid and movies that inspire generations," Johnson said. "Die Hard, Towering Inferno."

"The Fugitive, a little bit, [and] Cliffhanger," Thurber added, referring to the 1993 Renny Harlin-directed thriller starring Sylvester Stallone as a mountain climber and rescue ranger tasked with foiling a big-time heist.
"So this is an homage," Johnson explained.
Fans can watch the larger-than-life action hero try to save his family from an enormous burning building when Skyscraper hits theaters July 13.
"We were going to get married in the spring and we got pregnant," he explained. "Lauren felt like, well, you know, mama [doesn’t want] to take pictures being pregnant in a wedding dress, so we’re just going to wait and not quite sure when, but I know it’s going to happen."
