Rex is a film that, as soon as I saw the trailer, I was convinced already came out. Turns out I was right; it was released in America last year under the title Megan Leavey, and it took me perhaps longer than it should have to realise that they were the same film, and Kate Mara did not make two films about the same person.

Based on the true life story of a young Marine corporal whose unique discipline and bond with her military combat dog saved many lives during their deployment in Iraq, Rex was fairly well reviewed on it’s original release and is bound to strike a chord with dog lovers. That being said, it doesn’t look all that good, and this trailer in particular isn’t put together well.

Rex is out 12th March.
