The F1 cars in the film are mostly mocked-up Formula Three cars made to look like contemporary Formula One models, although the film also used footage from actual F1 races. Because Yamura Motors is a fictional race team, the producers struck a deal with Bruce McLaren's newly formed McLaren team to have his car, the McLaren M2B, to be painted with Yamura's colors. In two occasions, because the McLaren could not take part in these races, another car was painted in the same colours: Bob Bondurant's BRM at Spa, and at Zandvoort for the Dutch GP, the Lotus 25 BRM entered by Reg Parnell for Mike Spence. Some of the footage was captured by Phil Hill, the 1961 World Champion, who drove a modified camera car in some sessions during the Monaco and Belgian Grands Prix. This was some of the earliest experimentation with in-car cameras for F1, particularly in terms of first-person shots aimed at putting the audience in the position of the racers.
