# ‘Semper Fi’ trailer explores what happens when a hero breaks bad

![](<https://www.wearethemighty.com/wp-content/uploads/legacy/assets.rbl.ms/21106026/origin.jpg>)

West Point graduate Sean Mullin (*Amira & Sam*) returns to writing with *Semper Fi*, a film about a police officer and Marine Corps Reservist who is faced with an ethical dilemma when it comes to helping his brother in prison. *Murderball* director and co-writer Henry-Alex Rubin directed the film, which is filled with stars like Jai Courtney (*Suicide Squad*), Finn Witrock (*Unbroken*), and Leighton Meester (*Gossip Girl*).

But it's perfectly reasonable if you're most excited about [Recon Marine Rudy Reyes](<https://www.wearethemighty.com/mighty-trending/you-dont-know-rudy-reyes/>), who plays a role in the film and served as a military advisor for the production.

SEMPER FI Official Trailer (2019) Nat Wolff, Jai Courtney Movie HD

### Watch the trailer:

Courtney plays Cal, a police officer and Marine Corps reservist who decides to break his younger brother Oyster (played by *Paper Towns'* Nat Wolff) out of prison. In doing so, he'll question the system he has sworn to uphold, whatever the cost.

Some of the initial reactions to the trailer have included veterans and Marines saying the film goes against "what it means to be a Marine" but, given that the film doesn't come out until Oct. 4, 2019, I'd say it's probably too soon to tell. Furthermore, what "semper fi" means to one Marine might be different from what it means to another.

Besides, Mullin has a history of writing non-traditional veteran stories. *Amira Sam,* which Mullin wrote and directed, was about a veteran who comes home from war and his relationship with an immigrant. "I think every single 'veteran comes home from war' movie that's ever been made is about a veteran with post-traumatic stress, and I wanted to tell the first story about a veteran who comes home and he's okay but his country's lost its mind," Mullin told [Military.com](<https://www.military.com/undertheradar/2015/02/army-vet-sean-mullin-talks-about-amira-sam>).

Sometimes vets are heroes and sometimes they break bad. It sounds like Courtney portrays a Marine who is navigating both roads — it'll be interesting to see how the story plays out.

Either way, you can find out for yourself in October. In the meantime, feel free to keep the conversation going on our Facebook page: what is [Hollywood's responsibility](<https://www.wearethemighty.com/mighty-movies/military-in-hollywood-hire-veterans/>) when telling military stories?
