Kill Or Be Killed (1976, Ivan Hall)
Yes, apparently that Kill And Kill Again was a sequel! So we get this instead.
A chap who bears a grudge certainly asks our well spoken arse kicker to join his gang as he is recreating an old challenge with hopes of salvaging his dignity this time. Towards this we get a load of occidentals looking like corn beef getting their comeuppance daily (training montage), some romance (the only woman in the area easily falls for our chap natch ...) and a dwarf manservant!! A Sud Afrikan one at that
Ahem.
