Irish Mensa Lecture & Discussion: The Man Who Invented Christmas: Film Adaptations of Dickens' A Christmas Carol

Virtual meeting

No group assigned

"A Christmas Carol" (1843) is the most filmed and televised of Dickens' works. Many will warmly remember the 1951 Alastair Sim version, but how many are aware of "Carol for Another Christmas" (1964), a propaganda film produced in support of the UN, or "The Passions of Carol" (1975), which attempted to highlight the evil of the pornography industry? How do the different versions reflect the politics and culture of their own particular times? What makes a good Carol movie? Is it truth to the original or is it something else?

Why Everyone Should Read Science Fiction

Webinar

San Francisco Regional Mensa

Science fiction is not what you think. Since the dawn of the genre, sci-fi has been at the forefront of social-justice debates. If you suppose you know what science fiction is all about because you've seen "Star Wars," Hugo and Nebula award-winning bestselling author Robert J. Sawyer will show that "Star Wars" isn't science fiction, and introduce you to real sci-fi.
