Don't even talk about the street sequence. That's the worst thing even in the world of Superman, exect Lex Luthor having real hair in THE QUEST FOR PEACE: SUPERMAN IV. Can anyone explane that. He was bald, and wore a wig in I & II, and in IV, He was going bald, losing his real hair. EXPLANE!!!

One of the many budget limitations that plagued the film. They couldn't afford a bald wig, and they couldn't afford a hair wig.
