The car Hoppy refers to is a plain white GT40 with very early bodywork on Borranis.
BTW, you can read all about the film and the GT40s used in its production at:
A French Kiss With Death *-* Bentley Publishers - Automotive Books and Repair Manuals
Itīs a riveting read full of pics, facts and anecdotes such as the one of an extra who "borrowed" one of the Ferrari 512s for a night in town to impress a local girl...
