Is it a parody? Is it real? I guess we’ll find out on Saturday night when Lifetime airs “A Deadly Adoption” starring Will Ferrell and Kristin Wiig. Here’s the full trailer. You’re not sure whether to laugh or cry. The premise is that Will and Kristin are adopting a baby, and they’ve invited the nubile birth mother to live with them. You know, she seduces Will, goes crazy and there’s gunplay. It’s too bad there’s no promotion or publicity. It would be a hoot.
