Character actor Vic Diaz played the role of a mad biologist who plotted to conquer the world and destroy mankind by formulating a serum or formula that could increase the size of animals a hundred times. He tested it on a ‘tuko’ or gecko which turned into a giant menacing reptile.
Diaz reminded me of another bald-headed actor, Albert Dekker, the lead star in Dr. Cylcops (1940). Dekker, like Diaz also essayed the role of a mad scientist. Dekker, this time, shrinked human beings to a tiny size or a fraction of their normal size.
Tuko sa Madre Kakaw was based on the novel by Clodualdo del Mundo and serialized in Hiwaga Komiks. It starred Willie Sotelo, Nita Javier, Hector Reyes, Luz Valdez, Oscar Obligacion and Vic Diaz and directed by Richard Abelardo.
