So here we go.
(And again, this is not the only connection, and may not be the shortest, but I usually follow the first path I come across that leads to Holmes)
The always beautiful, very talented Reba McEntire (1955) -
was in the now cult favorite "Tremors" - 1990
which also starred "The six degrees" Kevin Bacon (1958) -
who starred in 1995's "Murder in the First"
which also featured the talented Gary Oldman (1958) -
who was the star of 2011's "Tinker, Tailor, Soldier, Spy" -
in which Benedict Cumberbatch (1976) participated -
who in "Sherlock" (2010 - present ) is, well, Sherlock -
There is also at least one more connection in "Tremors". Can ya find it?
There you have it, there you are.
