A patch of blue (1965)
Ghostbusters (1984)
Jaime Sommers (Bionic woman)
Tony Beretta (Beretta)

They all share one thing in particular, what is it?

Tough one. Here's a hint: I am looking for "digits".

Somebody can find what this means. All those names link to the Wu-Tang Clan.
What it has to do with Fingers I've yet to discover

Bedstor "digits" in this case meant "numbers" not "fingers".

And the other? Am I on the right track here?

Well I've checked that funny name "Wu-Tang Clan" and it looks like they are a "rap" group from New-York.

Nothing to do with "Digits" or the answer. Sorry.

The prefix 555 is often used in TV programmes and films for fictional telephone numbers.
One of the most popular telephone numbers used is 555-2368, which if you rang you could get hold of (supposedly), The Bionic Woman, The Ghostbusters, Tony Baretta and also apparently Jim Rockford. Think that covers all possible emergency's ! Just put it on my Speed dial list.
