Well, here's another great film to avoid, avoid, avoid.
Zorba the Greek is a film from 1964, not 1990. It was filmed in 1.85:1 widescreen. You want to buy a butchered version in which half the film has been hacked away? Go ahead. We all know that "full" screen is a marketing lie: a "full" screen is whatever aspect the film was originally. The 1.33:1 mutilation isn't "full" screen in any sense of the term.
Don't buy this turkey. Wait until a responsible DVD producer gives you at least a 16:9 version. Giving money to the people who deliberately mutilate films only encourages them -- this is only a ploy to get your money for the butchered version and then get your money again when the film as the director intended it is released.
