A Simple Favour trailer: Bridesmaids and The Heat director Paul Feig goes dark with new thriller

Paul Feig's a top-tier name in comedy now, thanks to the likes of Bridesmaids, Spy, and The Heat.

But with his latest, he's decided to take a rather different cinematic spin, adapting Darcey Bell's thriller A Simple Favour (or Favor, for US audiences) for the big screen.

With a trailer that promises to unleash Feig's "darker side", the story follows Anna Kendrick's Stephanie, a small-town mommy blogger whose mysterious new best friend Emily (Blake Lively), suddenly vanishes.

"People do terrible things for their own reasons," we hear Emily say, as Stephanie is left to uncover the mystery of what happened to her.

Henry Golding, Linda Cardellini, Eric Johnson, Jean Smart, Rupert Friend, and Andrew Rannells also star.

A Simple Favour hits UK cinemas 21 September.
