There's a few million dollars' worth of star power and a nickel's worth of plot in the lavish race-car melodrama Grand Prix. Among the participants in this annual cross-continent competition are characters played by James Garner, Yves Montand, Brian Bedford, and Antonio Sabato. Interested parties include Toshiro Mifune (his voice dubbed by Paul Frees), Adolfo Celi, and Claude Dauphin, while the women who agonize on the sidelines include Eva Marie Saint, Jessica Walter, and Françoise Hardy. The racing sequences are top-rank, cleverly utilizing those 1960s devices of helicopter angles and multiple screens. Oscars went to editor Frederic Steinkamp (among others) and the sound-effects supervisor Franklin E. Milton. Filmed on location, Grand Prix made back its cost about half a week into its run.
