1. Is when Lex Luthor opens a Jolly rancher and it is enormous
  2. Like the size of a bite size Snickers
  3. I don't know if they were shooting the scene and thought a regulation JR didn't play
  4. Or if there's a complicated backstory where Luthor has his JR's ordered to specifications
  5. It might the that he has his candy made to specifications. I haven't read the prequel comic so I'm not sure.
