Space is big — very big — and the new IMAX trailer for "Ad Astra" hopes to prove that seeing it on a large format screen is the only way to truly appreciate that.

The highly-anticipated sci-fi drama from James Gray ("The Lost City of Z") stars Brad Pitt as an astronaut who has dedicated his entire life to the exploration of space.

When Earth begins to suffer from a mysterious threat, Pitt is sent to the edge of the solar system to search for his father (Tommy Lee Jones), who went missing on a mission 16 years prior while experimenting on a material that could destroy all life.

The IMAX trailer focuses on the gorgeous visuals, as it depicts Pitt's astronaut seemingly falling from outer space toward Earth.

The movie looks to give Pitt his meatiest lead role in some time, possibly putting him in the Oscar race for Best Actor for the first time since 2011's "Moneyball." He also recently had a well-received turn in Quentin Tarantino's "Once Upon a Time in Hollywood."

Liv Tyler, Ruth Negga and Donald Sutherland also star.

"Ad Astra" opens in theaters September 20.
