The Devil at Your Heels is a 1981 documentary that chronicles the attempt of the stuntman and daredevil Ken Carter to jump a rocket-powered car over the Saint Lawrence River, a distance of one mile.
Technical problems included difficulties with the car (the fuel tank kept blowing up) and the ramp he was planning to jump off (it was bumpy and not structurally sound).
The backers, desperate to finish, believed that Carter had lost his nerve and called him to a meeting in another city, and then brought in another driver, American Kenny Powers, to attempt the jump.
[1] On 16 October 1993, The Devil at Your Heels was screened on Australian television as part of a special hosted by the cast of the ABC comedy series The Late Show.
A 2016 musical docudrama by John Bolton, Aim for the Roses, documents an album created by Mark Haney that was inspired by Ken Carter.
