Rachel McAdams and Dylan O’Brien are an acting duo I never expected to see, but I’m grateful for nonetheless after watching Sami Raimi’s “Send Help” over the weekend.

When I saw the trailer for this one, a boss (O’Brien) and his awkward, survivalist employee (McAdams) being stranded on a remote island following a plane crash, I already knew it would be good. You add in the fact that Raimi directed it (you may recognize his name from the 2000s “Spiderman” trilogy and, more recently, “Dr. Strange and the Multiverse of Madness) I was extra excited.

Raimi has a way of creating an unsettling universe filled with interesting camera angles that helps keep you on the edge of your seat every time.

With it making its way onto Hulu recently, I knew my time had come to take in this movie.

“Send Help” centers around Linda Liddle (McAdams), a brilliant strategist who has confidence when it comes to her love of survivalist knowledge but lacking in the office, who is expecting a big promotion at her company when new CEO Bradley Preston (O’Brien) takes over.

However, the promotion promised by Bradley’s father ends up going to one of his former fraternity brothers, Donovan. We see pretty quickly that Bradley is arrogant and extremely focused on appearances, deciding that Linda lacks any people skills and the right aesthetic for the promotion.

When Linda confronts him about this, he invites her to join him and Donovan on a trip to Bangkok to finalize a merger.

Things, of course, take an intense turn when the plane crashes during a storm, stranding Linda and Bradley on a remote island somewhere in Thailand.

The roles between the two are suddenly shifted as Bradley is completely out of his depth and Linda suddenly finds purpose… though some of that is enacting some amount of revenge on Bradley with the shifted power dynamic.

What follows is a back and forth filled with betrayals, unity and lots and lots of twists as Linda looks to keep her hold over Bradley for as long as possible.

Seeing McAdams get the opportunity to flex her acting skills as Linda was extremely fun. As many may know, she’s well known for her role as queen bee Regina George in “Mean Girls” and lovesick southern belle Allie Hamilton in “The Notebook.”

More often than not, and in other movies beyond these, she’s a more confident, perfect person. However, Linda is entirely opposite this.

She’s awkward, talks to her pet bird and doesn’t really know how to relate to anyone. (I will note it was insane they thought they could make her not look pretty, given she’s — you know — Rachel McAdams.)

She played this role perfectly while dropping little crumbs along the way to showcase there’s a bit of steel under Linda’s bumbling exterior, that culminates perfectly in the final moments of this movie.

I’m familiar with O’Brien in many different roles: from awkward teen Stiles Stalinski in MTV’s “Teen Wolf” series to playing dual roles in the more recently released movie “Twins.” However, it’s still always a treat to see how he decides to bring characters to life.

In my opinion, Bradley is constantly taking a step forward and two step backs during his time with Linda. Personally, I’d be grateful to have washed up on an island with a woman who knows how to keep me alive. However, Bradley doesn’t always feel the same way.

Throughout the movie you watch as he tries to keep his role as Linda’s boss, but also bends to her will when he realizes he’s not cut out for survival on his own.

It’s a constant push and pull between the two of them where the lines between truth and manipulation are blurred.

Mix in Raimi’s penchant for intriguing cinematography, gore and body horror and you’ve got yourself a tense movie filled with quite a lot to take in.

If you aren’t big on gore and grossness, I’d probably steer clear of this movie. There were a few scenes, particularly near the end, that even had me feel a little squeamish. However, if none of that bothers you, I highly recommend giving it a watch.

O’Brien and McAdams are great scene partners and the story itself is something I’ve never seen before and really enjoyed.

Let me close with something for my “Yellowjackets” fans: Linda Liddle is Misty Quigly in an alternate universe and a different plane crash.
