The Boston-based feature comes from ‘Mystic River’ scribe Brian Helgeland.

An A-list trio has been assembled for a hot new package, Finest Kind.

Jake Gyllenhaal, Ansel Elgort and Zendaya will star in the crime drama from Brian Helgeland, the Oscar-winning writer-director behind Mystic River, L.A. Confidential and AKnight’s Tale.

Producing are Krasnoff/Foster Entertainment and Dan Friedkin and Bradley Thomas of Imperative Entertainment. Gyllenhaal and his Nine Stories partner Riva Marker are also producing. 30WEST is financing the film.

STX Entertainment is handling international distribution on the new project, which will be introduced to buyers at Berlin’s European Film Market. CAA and Endeavor Content are repping domestic rights.

The story centers on two half-brothers (Gyllenhaal and Elgort) that are reunited as adults after being raised by different fathers. When one discovers his estranged father has only months to live, he strikes a dangerous deal with a crime syndicate, putting him and his brother on a collision course with the Boston underworld.

Gyllenhaal, who is no stranger to the crime drama genre as the star of Night Crawler and Nocturnal Animals, will next be seen in the Annapurna Western The Sisters Brothers. He is repped by WME and Bloom Hergott.

Zendaya is currently in theaters with the awards contender and sleeper hit The Greatest Showman, and is set for the sequel to Spider-Man: Homecoming. She is repped by CAA, Monster Talent and Skrzyniarz & Mallean.

Next up for the Baby Driver star and onscreen terminally ill teen Elgort is Warner Bros.’ The Goldfinch adaptation, in which he leads a cast that includes Nicole Kidman and Sarah Paulson. He is repped by CAA, Brookside and Morris Yorn.

Helgeland won an Oscar for writing L.A. Confidential and directed the Jackie Robinson biopic 42, which starred Chadwick Boseman, and Legend, a crime drama starring Tom Hardy. He is repped by CAA and Jackoway Tyerman.
