Robert Redford - (1936)
was in one of my favorite movies ever, 'Situation Hopeless. . But Not Serious' - 1965
with the great Sir Alec Guinness - (1914 - 2000 )
who was in a movie called, 'The Lavender Hill Mob' - 1951
which featured Sid James - ( 1913 - 1976 )
who participated in 1959's 'Upstairs and Downstairs'
which also included Michael Craig - ( 1928 )
who was featured in 1961's 'Mysterious Island'
which starred the beautiful Joan Greenwood - ( 1921 - 1987 )
who played Beryl Stapleton in 1978's 'Hound of the Baskervilles'
Again, I just went with the first film that offered a connection to Holmes, several other movies may also offer that connection.
So there you have it, there you are.
