Brad Pitt recruited the acclaimed composer to provide the theme for his next Formula One film, Apex.
The composer is most known for scoring some of the greatest films of all time, including Interstellar, Gladiator, and The Lion King.
According to The Sun, Brad invited Han to spend time with him and Mercedes driver Sir Lewis Hamilton at the Austrian Grand Prix so that the musician could experience what he was going to put into music.
"Hans wrote the score for the F1 film Rush in 2013, so it was a no-brainer for Brad to have him on board," one insider told the newspaper.
"He personally invited Hans down to a race to spend time with him and Lewis on the grid to get his creative juices flowing," according to the report.
In addition, the insider stated: "There are more announcements being made about the film in the coming days and from what Brad has heard of Hans' score for Apex, it sounds like he's on to a winner."
According to sources, Hans also confirmed his involvement in the film and played the Austrian national hymn on his electric guitar.
