Not long after completing his work for "Chitty Chitty Bang Bang" in 1968, Justice suffered a severe stroke, which signalled the beginning of the end for his career. He appeared in a number of films afterward, albeit in less prominent roles (i.e. playing his best known character of Sir Lancelot Spratt for the final time in "Doctor in Trouble" (1970), featured only briefly in several scenes). He suffered a further series of strokes, which left him unable to work. He was declared bankrupt in 1970, and he died penniless in 1975. His ashes were buried in a north Scotland moor near his former residence in the Highland village of Spinningdale.
