ET caught up with Chris Hemsworth at the Toronto International Film Festival over the weekend, where he and his cast mates were a bit apprehensive that their new high-octane racing thriller Rush was to screen for, among others, Niki Lauda, one of the Formula One drivers portrayed in the film.
Lauda is played by German actor Daniel Bruhl (Inglourious Basterds) in the Ron Howard film, which details the bitter rivalry between him and another Formula One champion, James Hunt.
Luckily, as Hemsworth noted, the pressure was alleviated a bit, because Niki had already seen the film, and praised it.

"I saw Niki [at the London premiere of Rush]," commented Hemsworth, adding that, "he said he was blown away by the whole thing... and wishes that James [Hunt, Niki Lauda's rival whom Hemsworth portrays in the film] could have been here to experience it too."
Check out the video above to hear more from Hemsworth, director Ron Howard, and co-stars Olivia Wilde and Daniel Bruhl, from the Toronto International Film Festival.
Rush premieres in theaters September, 27, 2013.
