Trivia / Sinister Stepsister

• Market-Based Title: Shown in Britain as The Stepsister.
• Playing Against Type:
  • Annika Foster's other Lifetime movie roles have tended to be as the heroine or otherwise a "good" character, making her turn as the villain here a rarity.
  • Matt Pohlkamp was in a whole rash of Lifetime movies at the end of 2021 and the beginning of 2022, but for the majority of them he played a lecherous villain. Here, he's a Happily Married Nice Guy father.
• Spoiled by the Cast List: The movie's IMDb page flat-out gives away the story's twist by listing Gigi Gustin's character as "the real Carlee Byrne".
• Those Two Actors: Matt Pohlkamp (Jeff) and Tu Morrow (Ella) were previously in Lifetime's Deadly Daughter Switch, also as father and daughter—sort of (it's a Switched at Birth story and she's not really his biological daughter after all).
  • There's also Annika Foster and Jacob Taylor, who previously appeared together in Lifetime's Deadly Infidelity.
