Surprising Secrets from the Set of Little House on the Prairie

During filming, Alison Arngrim developed a crush on Radames Pera, who played John Sanderson, Mary Ingalls’s love interest. Arngrim, a few years younger, hoped for something more off-screen, but Pera didn’t see it that way and gently turned her down.

He felt she was too young for him at the time, though the two remained friendly on set. For Arngrim, it became one of those lighthearted memories from her teenage years in Hollywood — a harmless crush that never quite became reality.
