Three of his novels have been filmed. ''[[A Twist of Sand]]'' (1968) co-starred [[Honor Blackman]] and [[Richard Johnson (actor)|Richard Johnson]], director [[Terence Young (director)|Terence Young]]'s original choice for James Bond. ''Dirty Games'' (1989), based on ''In Harm's Way'', co-starred [[Jan-Michael Vincent]].

''The River of Diamonds'' (1990) had been set for production in the 1960s. During the 1980s [[Brian Clemens]] wrote a script. [[Sylvester Stallone]] - who asked for {{USD|9M}} and a share of the profits - and [[Tom Selleck]] - who asked for {{USD|1.5M}} and a share of the profits - were approached to star, but asked too much money which the production couldn't afford. A journal describes this as South Africa's "most ambitious film project" with what was at the time to have been the biggest budget financed by a South African producer estimated to have been between two and three million [[South African rand|Rand]].<ref name="SAD">{{cite journal|journal=South African Digest|year=1984|page=199}}</ref>
