Hush...Hush, Nellie Oleson!(2019)

After shooting a low-budget horror film, director Kelly Hughes gets a chance to work with his childhood idol Alison Arngrim, the actress who played the scheming Nellie Oleson on TV's Little House on the Prairie. But fitting Arngrim into the finished product becomes an exercise in futility as Hughes shoots increasingly absurd (and gory) scenes with Arngrim that don't have much to do with the original plot. Featuring extensive interviews with the cast and vivid film clips, "Hush...Hush, Nellie Oleson!" is a love letter to low-budget filmmakers and the former child stars who enable them.
