Men In Black (1997).

Still fun, shame the series went of the rails because there was a lot of comic potential for the premise and the first film only really scratched the surface.

The alien effects look so much more convincing than those in the PT which was two years later.

Men In Black is a comic book adaptation so the characters are meant to look a bit cartoonish but this guy:

Three red lights.

The MIB fellow was more man in suit than CGI, so that makes sense.

It makes me smile to know Rick Baker is still making monster suits for movies.
