Liz Moore was riding in boyfriend John Richardson's BMW, when they crashed. Richardson who had been a special effects supervisor on
The Omen (1976) was on location in Holland during production of
A Bridge Too Far (1977). The crash was believed to be a result of the sinister curse on those who involved in the making of The Omen. The incident happened just after midnight on Friday August 13, 1976. The head-on collision beheaded Moore (a real-life echo of Jenning's decapitation on that film), but left Richardson alive, but dazed. When he got up after the collision, he noticed a signpost nearby pointing to the nearest town of Ommen, which is twenty kilometers away, but the kilometer marker where it happened, was 66.6.
