Following my recent Nico Mastorakis fascination, I've done a great service & compiled a list of Mastorakis titles available on dvd in the US. There are multiple editions/pressings of most. In general, the '2003' editions on Omega Entertainment are the preferable releases.

Mastorakis Collection on DVD:

Blind Date
Bloodstone (writer/producer)
.Com For Murder
Glitch!
Grandma's House (producer)
In The Cold Of The Night
Hired To Kill
Island Of Death
The Naked Truth
Nightmare At Noon
Ninja Academy
Skyhigh - A Summer On Fire
The Time Traveller
The Wind
The Zero Boys

I also stumbled across a short Mastorakis interview about The Zero Boys!

BONUS Mastorakis film trailer for Nightmare At Noon, another one starring Wings (Vice Squad, Deadly Force) Hauser!
