Corrected entry: In Highlander 2 they say that all Highlanders are born on another planet. But in the first Highlander, McLeod is born in Scotland.
Corrected entry: This error is in the scene with Katana and the cab driver Jerry. When the cab is arriving at the TSC meeting building look to the extreme right and you can see the sun rising between two buildings and the sky is a nice golden yellow colour. Hang on...isn't there supposed to be a shield up leaving the planet in constant darkness with fancy streams of colour? Sack the Special Effects guys. This was in widescreen - may not be visible in pan & scan.
