After graduating from RADA, Beckley started working for various provincial repertory companies, eventually settling with a company near London (Bromley Repertory[REF]) which opened up opportunities for television work [REF].
On television he guested on shows such as Manhunt, Callan, Jason King, Special Branch, and perhaps most notably as the villainous Harrison Chase in the popular six-part Doctor Who serial The Seeds of Doom [REF].
