(CAPE CANAVERAL, Fla.) — Brad Pitt, star of the new space movie “Ad Astra,” had a burning question for a real-life astronaut: “Who was more believable? Clooney or Pitt?” In a televised call Monday, NASA astronaut Nick Hague answered Pitt — “absolutely” — getting a big laugh. Pitt’s Hollywood pal George Clooney starred in the 2013 space film “Gravity.” Hague and the rest of the International Space Station crew previewed “Ad Astra” a few weeks ago.
