Underworld Collection (Quadrilogy)

[Astaire]

Great cover but, just my taste, I admit it, for the excess of actors names on the front cover.

And it would have been great if you'd use the correct word to express what you wanted (a quartet of films) that is: TETRALOGY. QUADRILOGY is an invention of an illiterate employee of Fox for the issue of the Alien collection and it sadly stuck. But to this day it means nothing. No offense intended. Just my 2 cents.
