Most people wouldn't notice this on any film; but in any movie that is based earlier than the 90's, the glasses on any given character have the green reflective option. (You know, the glare resistant sheen they put on)...obviously since these glasses were made in the 90's the authenticity of the character's clothing and accessories are of lesser...well...authenticity.

The president of the US has them on in this movie (just watch for a window reflection; it's green)
