Sean Penn's Heat-Related Collapse on the Set of *Little House on the Prairie*

During the filming of *Little House on the Prairie* in Simi Valley, California, the cast faced extreme heat that led to multiple instances of heat exhaustion. Alison Arngrim, who portrayed Nellie Oleson, recounted on *The Patrick LabyorSheaux* podcast that the conditions were so severe that the crew kept buckets of ice water and salt tablets on hand to help the actors cope. The heat was particularly intense during scenes that required the child actors to gather around a hot forge, which contributed to the challenging filming environment.
