I had the pleasure of viewing this film in the presence of George Romero himself a couple years ago, and I learned a couple interesting from him:

Leslie Nielsen's maniacal laugh has a funny story behind it. Leslie would carry a fart machine around on set, and activated it every time he needed to do his evil laugh.

Also, it's illegal to just go out and catch a bunch of cockroaches and use them in your film, apparently, so they got the cockroaches from a cave in a different country. The cave was so full of cockroaches that they just dug a hole and waited a brief amount of time for the hole to fill up with thousands of them.
