'Rush' as a James Hunt and Niki Lauda romantic comedy

'Rush' stars Chris Hemsworth and Daniel Bruhl "invented" a "romantic comedy" between their characters.

The actors play Formula One racers James Hunt and Niki Lauda, who were known for their fierce rivalry during the 1976 F1 season, in Ron Howard's new biopic, but the stars were much friendlier than their real-life counterparts.
