Diamonds on Wheels is a 1973 British family comedy film directed by Jerome Courtland and starring Peter Firth, Patrick Allen, George Sewell, Derek Newark, George Woodbridge and Barry Jackson.

Diamond thief Billy double-crosses his gang and drives off with the proceeds of a robbery but is killed when his car crashes.

The Monthly Film Bulletin wrote: "Disney's first British production for some considerable time (efficiently directed by Forties matinee idol Jerome Courtland) fares well enough as a children's thriller, while the rally itself provides the setting for multiple ambushes and some diverting riddles.

Unfortunately, the film runs out of steam once it leaves the racetrack, and the long slapstick sequence in the warehouse brings everything to a rather tired and arbitrary conclusion, making very scrappy use of the possibilities of the location.

There is, however, plenty of amusement to be had from the performance of Dudley Sutton, playing Peter Lorre to Barry Jackson's Raymond Massey in a partnership strongly reminiscent of Arsenic and Old Lace.
