Seven Degrees of Sherlock Holmes - #16 - Reba McEntire

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.
