Laughter Is a Gift from Heaven (1963)

In vain, the successful industrialist, Xenophon Charitidis, tries to persuade his lively young daughter, Lisa, to get married with his gangling and kind-hearted partner, Prokopis. However, transforming him into a desirable man is a nearly impossible task, unless a truly beautiful and famous woman such as the seductive femme fatale, Gisela Dali, becomes, somehow, the unlikely Casanova's mistress. That would do the trick; nevertheless, what happens if the news of this bogus affair reaches the blonde superstar--and God forbid--her jealous fiancé, Vrasidas?
