Adaptation A: Further character design

 I've added items or merely just edited the design of these characters to add more personality to them and to bring in context through this detail.

I've made the Christopher Reeve rendition of Superman have smaller pants to suit how they dressed in the 70's/80's. They some how saw a man in speedo's as masculine and he-manish but hey, whatever floats their boat.

The 1950's Superman I've done the opposite and made his pants bigger and Simon Cowell-ish, which is the way he would have worn them in that time period.

For Marlon Brando's character Jor-El I've made his outfit glow like it did in the movie because of his omnipotent persona.

Richard Pryor's character Gus would stereotypically have a pen in his pocket, being a computer programmer. And his actual persona as a comedian would stereotypically have a 'rolled up something' as Alan suggested.

Margot Kidder's character Lois Lane was a 70's character so I added the oversized 70/80's collars and added a pen and notebook as she would stereo typically be seen with this as a reporter.
