As the series was coming to an end, this was the last episode to feature the outrageous Penguin. The multi-talented Burgess Meredith was so popular that the producers always had a script ready to go, depending on his busy film and tv schedule. He was more than happy to oblige, and it showed. Doing a little research, it turns out that Meredith's over the top performance as a mad scientist (who produced earthquakes) in the WILD WILD WEST (1965), may have inspired producers to cast him as the Penguin the following year. He was a brilliant, one of a kind actor. Hands down, the best choice. Here, chain-smoking, quack quacking Penguin develops an ingenious plan to infect Gotham City's money supply. If that's not enough, he threatens Batman he will release thousands of fruit flies to invade Gotham. Heaven forbid! Former skater and model Monique van Voreen makes her second appearance as Penguin's bad girl, Miss Clean. Van Voreen reportedly spoke as many as six languages, and at age 40 (and looking terrific) was the oldest of villain girls. Look for Charles Dierkop as Dustbag, long playing sidekicks and hoods in tv cop shows and films. The next villain to appear is Calamity Jan, played by Dina Merrill, in a brief cameo. Merrill, enormously popular in dramatic roles (BUTTERFIELD 8, THE SUNDOWNERS) gained a new generation of fans with this offbeat part, possibly a replacement of sorts for Eartha Kitt's Catwoman.
