"The Rotters" is predictable but fun, uniting series veterans Gerald Sim ("The Radioactive Man," "Mission to Montreal," "The Wringer," "Dial a Deadly Number") and Jerome Willis ("Intercrime" and "How to Succeed....at Murder") as a pair of gentlemanly assassins who despise the working class because they're "so working class." Representing the firm Wormdoom, they bump off the members of the Institute of Timber Technology, using a special spray concocted with spores that dissolve wood on contact (a story that recalls the best of Emma Peel). Directed with panache by Robert Fuest, also featuring John Nettleton ("The See-Through Man"), Harold Innocent ("The Medicine Men"), Toni Gilpin ("Death on the Rocks"), John Stone ("The Secrets Broker" and "The Joker"), Charles Morgan ("Brought to Book"), and Noel Davis ("A Funny Thing Happened on the Way to the Station").
