No 10621 was a special order for Steve McQueen in 1967, while he was filming The Thomas Crown Affair. McQueen, known for lightly customizing his cars, sent the car to be repainted Chianti Red prior to taking possession. He also requested that No. 10621 be fitted with the Borrani wire wheels from his 275 GTB N.A.R.T. Spider, which was a victim of an unfortunate earlier crash, as well as a few minor additions.

Once complete, McQueen took delivery of the car while on the set of his legendary 1968 crime-drama Bullitt. It remained the only Ferrari in his stable of sports cars for almost five years, before passing onto fellow actor Guy Williams, of Zorro and Lost in Space fame, in 1971
