Space isn't the final frontier in the new trailer for "Ad Astra" — it's the psychology of daddy issues.

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 new trailer is even moodier and introspective than the first. The movie looks to give Pitt his meatiest role in some time, possibly putting him in the Oscar race as an actor for the first time since 2011's "Moneyball."

Liv Tyler, Ruth Negga and Donald Sutherland also star.

"Ad Astra" opens in theaters September 20.
