Bleecker Street has unveiled the first trailer forMegan Leavey, the true-story drama about a young marine corporal who forms a lifelong bond with a military dog.Kate Marastars in the title role as Leavey, a marine who was assigned to clean up the K9 unit in Iraq where she formed an unlikely bond with a particularly aggressive dog, Rex. The two ended up serving together and were both injured by an IED explosion, after which Leavey fought for the right to adopt Rex as her own.
Mara is a particularly underrated talent who sometimes is overshadowed a bit by her sister,Rooney Mara, who isalsoa terrific actress. But while Kate hasn’t gotten roles as flashy asGirl with the Dragon TattooorCarol, she’s a great actress in her own right, particularly shining on Netflix’sHouse of Cards. So it’s nice to see her leading a drama of her own here, even if it looks to be a crazy tearjerker—especially if the dog dies.

Curiously enough,Bridesmaidsco-writerAnnie Mumaloco-wrote the script withTim LovestedtandMusic of the HeartscribePamela Gray. Behind the camera as director isBlackfishhelmerGabriela Cowperthwaite, making her narrative directorial debut.
