The characters of the treasure-hunting film, which is based on the beloved Disney attraction and stars Emily Blunt as botanist Lily Hughton and Dwayne Johnson as riverboat skipper Frank Wolff, come across an underwater lever near the end of the film, which they have to pull down in order to continue on.

The entire scenario was shot in two weeks in an underwater set on an Atlanta studio lot, with the exception of the CGI piranhas. The majority of Blunt and Johnson’s underwater acting was done.

Ian Seabrook, the film’s underwater cinematographer, spoke with Insider about the difficulties in executing the scene and why he was surprised with Blunt’s performance considering that she had never shot a scene underwater.

The character Lily played by Emily Blunt in “Jungle Cruise” finds it difficult to pull down. Disney+Emily Blunt performed an underwater sequence without ever having experienced fear.When it comes to underwater photography, Hollywood only uses a select few DPs like Seabrook. Having worked on films ranging from Deadpool 2 to Christopher Nolan’s “Insomnia,” he has the experience to demonstrate that underwater filming is not for the timid.”On ‘Batman v Superman’ myself and Amy Adams both got ear infections from the rust from the underwater set because the crew didn’t use marine-grade materials,” Seabrook stated to Insider. “Having your ears vacuumed is not a pleasant way to spend your afternoon.”Seabrook was therefore entirely focused on his work when he was contracted to do the underwater scene for “Jungle Cruise.””We went over the sequence, went over the blueprints; I talked to the art department because they had begun building the rough blueprints for the set,” he stated.

He knew The Rock was set to go because he had already worked with Johnson. What about Blunt, though?”If she was fearful she did not communicate it, she was game,” Seabrook stated.

On each take of the sequence, Johnson and Blunt held their breath for 30 seconds.The water sequence has two places. The first picture is of Frank and Lily diving into the water at La Luna Rota. It was shot on an outdoor set. The main difficulty, according to Seabrook, was keeping the proper distance between himself and his waterproof camera from Johnson when the latter entered the water during this part of the session.I have taken cruises on all five of Disney’s ships. There are two that stand out as my favourites, and only one that I’m not eager to book again.I travelled to Costa Rica’s top destinations for 12 days, including the Nicoya Peninsula and Cloud Forest. Three locations I would visit again in a heartbeat, but there is one tourist trap I will never fall for.

“When Dwayne took his first breaststroke, the first take he did he ended up right on top of me,” Seabrook said. “I was able to obtain enough space to grab the photo when he dived down because I was able to rapidly lunge back underwater and balance on the tips of my fins after realising how powerful he is at swimming. I essentially needed to swim at the same speed as him.”

The rest of the sequence took place in the tank.

Because the set has a ceiling structure, the obvious emergency exit for Blunt to take, swimming straight up to the surface, was taken away. So Seabrook said he devised with Blunt and her stunt double Lauren Shaw another emergency exit — they would swim to the right or left of his camera and then swim to the surface if anything went wrong.

The DP said knowing where to bail out is important as the actors are doing everything while holding their breath, and panic can set in if you feel you are losing breath and don’t know how to get to the surface.

Seabrook said both Johnson and Blunt held their breath for up to 30 seconds when doing takes for the sequence. And they did this over days of shoots for two weeks.

But that wasn’t the only waterwork. Seabrook and Blunt still had to team up to pull off the sequence’s finale.
