A trailer for the space sci-fi drama Ad Astra appeared Wednesday, launching Brad Pitt into full hero mode as an astronaut.

Intrepid spaceman Roy McBride (Pitt) must travel into the cosmos to follow up on an extraterrestrial-seeking mission commanded by his father (Tommy Lee Jones). Roy is told that his pioneering pop was experimenting with a highly classified material that could threaten our entire solar system. All life would be destroyed. Were counting on you to find out whats happening out there.

No pressure!

McBrides wife (Liv Tyler) already mentioned a surge that is creating chaos on Earth, so Roy better high-tail it into the stratosphere before its too late.

The film is scheduled to open Sept. 20 after previous release dates were scrubbed, Deadline previously reported .

Before shooting the film, director James Gray (The Lost City of Z) compared it to a literary classic.

Its kind of a Heart of Darkness story about traveling to the outer edge of our solar system, he said. I have a lot of hopes for it but it is certainly ambitious.

Watch the trailer above.
