Laser Force's game concept borrowed?

Just taking a nostalgia romp through the game section and had a comment to add about Huibert Albars' Laser Force game. Well, two things I discovered years later and thought I'd share here.

First is the game concept itself, which doesn't appear to be entirely original. It looks to have heavily borrowed from the 1983 video arcade game "Marvin's Maze" by SNK Electronics. Here's a screen shot to compare:

The second bit, the title screen is a colorized poster scan of a low budget 80's Italian b-movie called "2019 - After the Fall of New York". Here's the movie poster:

(I anonymously sent in a copy of that movie poster several years back, I see it got noticed looking at the review comments). :)
