Find criteria relationships

You know when you feel like something is similar to something else and you want to know if it's linked?

Like, why are Pulp Fiction and Reservoir Dogs similar? IMDB. It's Quentin Tarantino Bitchessss....

Or what does Seth Green and Nathan Fillion have in common?
IMDB. Pretty much everything Bitchessss....
In fact IMDB you further. Based on this relationship you might also be interested in Alan Tudyk or even Heath Ledger

Seriously though. Can this or has this been implemented.
