The more they renovate the house, the more powerful her spirit grows... A fixer-upper is home to more than peeling paint and leaky plumbing (although those issues can seem like they're straight out of hell if you've encounterd them on your home improvement adventures) in the teaser trailer for Andy Mitton's The Witch in the Window, coming soon to Shudder in the US:
"THE WITCH IN THE WINDOW focuses on separated father Simon and his estranged twelve year-old son, Finn, who head to Vermont to repair an old farmhouse and encounter the malicious spirit of a previous owner, an infamously cruel woman named Lydia. With every repair Simon makes, he’s also making her spirit stronger…until a terrifying encounter leaves him doubting whether he can protect his son from the evil that’s making its way into their heads, and hearts.
Starring Alex Draper as Simon and introducing Charlie Tacker as Finn, with Greg Naughton, Arija Bareikis, and Carol Stanzione. THE WITCH IN THE WINDOW was written and directed by Andy Mitton and produced by Richard W. King. Clark Freeman served as Executive Producer."
