Sir Graves Ghastly was a character created by Cleveland-born actor Lawson J. Deming (1913–2007) for the popular television show of the same name.
The show followed a consistent format of back-to-back horror films, interspersed with brief sketch comedy pieces featuring the many characters.
The program was originally billed as Sir Graves' Big Show, but later became known simply by the character's name.
Sir Graves Ghastly had its longest run Saturday afternoons on WJBK, TV2 in Detroit, from 1967 to 1982: fifteen seasons in all.
The growing popularity of televised sports in the early 1980s, particularly college football, sent Sir Graves into hiatus in November 1982.
