Cancer got around the cast and crew.
Cancer obviously isn’t contagious, but a curse isn’t out of the question. Six actors and crew members ended up with cancer – including Michael Landon (pancreatic cancer). Allegedly this spike in cancer is due to a chemical dumping ground that was near the set.
Alison Arngrim really wanted to be on the show.
Arngrim would go on to audition for three different roles before landing her character, Nellie. Persistence pays off, apparently.
