Brad Pitt and Marion Cotillard star in the first trailer for their upcoming spy thriller, Allied.

Pitt stars as Max Vatan, a British intelligence officer during World War II who encounters French Resistance fighter Marianne Beausejour (Cotillard) during a mission in Casablanca that forces them into a pretend marriage so their cover isn’t blown.

The pair is reunited later in London and fall in love, though the horrors of war threaten to destroy their relationship.

The cast also includes Lizzy Caplan, Matthew Goode and Jared Harris and the film is directed by Robert Zemeckis.

Allied is expected in cinemas in November.
