A Little Piece of Home (1996)

Victor Brandt: Professor Hamilton

Quotes 

• Professor Hamilton : The fact that your body chemistry absorbs the radiations so readily, leads me to believe that you share with it a point of origin.

  Superman : You mean it came from Krypton?

  Professor Hamilton : More than likely it is Krypton, or rather a small piece of it. 'Kryptonite' if you will.

• Professor Hamilton : The green radiation could have been created by the energy released in a cataclysmic explosion which destroyed your planet. There is one bit of potentially helpful data. Its radiation can be shielded by element atomic number 82.

  [he tosses a small case to Superman, who cowers upon catching it, but nothing happens] 

  Professor Hamilton : Lead.
