Montreal planetarium brings city scenes to big screen with groundbreaking 360-degree film

When the lights go down under the big dome at the Montreal planetarium, the audience is transported not to a far-away moon or alien solar system,but to a surprisingly familiar scene.

Captured in high-quality 360-degree video, images of Montreal in summerflood the 18-metre screen: drummers beat their tam-tamsin front of the Georges-tienne Cartier monument in Mount Royal Park, locals ride bikes on tree-shaded paths, young people balance on slack lines strung between two trees.

These are the opening scenes of the newest offering fromthe Rio Tinto Alcan Planetariuma show about life on other planets that starts right here in Montreal.

"I saw all the magnificent people and the energy happening there, and I said to myself, 'This must be filmed in 360-degree,'" said astronomer SbastienGauthier.

"It's the perfect scene for the dome. There's so much passion everywhere.'"

Gauthieristhe executive producer, project manager, director and photo director of the new show, EXO.

"When you look at humans performing live music at those events, and tourists and neighbours enjoying the partyyou see everything. You see joy;you see love;you see music, passion and some sort of science and engineering," he said.

"For me, this gathering represents what is good about humanity."

Are we alone?

At its heart, EXO focuses on the idea of extraterrestrial life, posing the question, "Are we alone?"

Starting on Earth, with a montage of life in the natural world some of which was shot at the nearby Botanical Gardens and the Biodomethe film then takes viewers into the outer reaches of our solar system.

The show is educational, offering information about what scientists know about alien life and how they continue to research it, but it also invites viewers to think about the bigger picture on their own terms.

"It gives us a philosophical point of view about our life," said Gauthier.

Twophilosophers were consulted on the project, including UQAM'sChristophe Malaterre, who holds the Canada research chair in life science philosophy.

From the distant,cold exo-planets that can't sustain liquid waterto the tiniest builder ants or a group of poisonous blue dart frogs,the film strives to remind its audience that life everywhere is precious.

Ambitious undertaking

The show offers stunning visuals of life on earth, including the 360-degreeimmersive video shot specifically for the presentationan ambitious undertaking with its own set of challenges.

Because the video camera rotates in all directions, its difficult to hide crew and equipment, saidGauthier. Moreover, modifying the existing technology to suit the team's needs requiredmore than a little tinkering.

"Every movie we make, we push the technology forward," said Gauthier. "For EXO, we modified a cinema camera."

The planetarium's film team had to develop new ways of filming and producing 360 video in order to get the shots they needed for such an immense platform.

The large dome at the planetarium is bigger than an IMAX screen, and the 360-degree video is hard to edit and to conceptualize on a regular computer monitor.

Gauthier and his assistant took matters into their own hands, building a miniature dome maquette where they could preview the video in 360-degree projection.

"We built a foam core dome in about two hours," he said. "It's right in the middle of our visual effects studio. We use it daily."

EXO is running now at the Rio Tinto Alcan Planetarium, just off of Viau Street next to the Olympic Stadium. The film is recommended for viewers aged seven and up, and it runs 40 minutes.
