Blake Lively And Anna Kendrick Get Tangled Up In A Mystery In ‘A Simple Favor’ Trailer

Forget the wine—get your martini glasses ready for the newest suburban thriller of 2018.

It’s a simple cocktail recipe, just mix a bit of Gone Girl with The Girl on the Train, give it a shake. Garnish with a twist, and you’ll have Blake Lively and Anna Kendrick’s new mystery movie A Simple Favor.

The new thriller from director Paul Feig (Spy, Bridesmaids) stars Kendrick as Stephanie Ward, a mommy vlogger who goes looking for answers after her best friend Emily Nelson (Lively) suddenly disappears. Joined by Emily’s husband—played by Henry Golding (Crazy Rich Asians)—Stephanie uncovers secrets she never expected to, including betrayal and possible murder.

Given his past work, Feig is a director who has consistently shown an interest in eccentric female stories and A Simple Favor looks to be just that as Kendrick and Lively prove to make a promising on-screen duo.

With chilling flashes of police sirens, a violent car crash, and smirky glances from Lively, her character reminds us, “Everybody has a dark side. Some of us are better at hiding it than others.”

Going off of the trailer’s ominous vibe and retro aesthetic, A Simple Favor looks to be the next book adaptation trying to capture the cultural power of David Fincher’s Gone Girl, which Tate Taylor’s The Girl on the Train tried, and failed, to do so in 2016. With only teaser trailer to go off of, we’re still not sure whether A Simple Favor will be able to recreate Gone Girl’s murder-mystery popularity.

In anticipation of the trailer’s release, Lively deleted all of her Instagram photos this past Monday, removed her profile picture, and changed her bio to the question, “What happened to Emily?” Over the last few days, Lively has also been unfollowing everyone she previously tracked (including hubby Ryan Reynolds), and is now only following women named Emily Nelson—38 of them and counting.

The whole thing is giving us some serious Serena van der Woodsen vibes, if Serena was in her early 30s, working in New York City, and living in a fancy suburban mansion, being as mysterious as ever.

Based on the bestselling novel of the same name by Darcey Bell, A Simple Favor was written by American Horror Story screenwriter Jessica Sharzer and also stars Andrew Rannells, Linda Cardellini, Jean Smart, and Rupert Friend. The film is set to hit theatres September 14, 2018.
