PARIS (REUTERS) - Brad Pitt and Marion Cotillard were in Paris on Sunday (Nov 20) to present "Allied", a romantic espionage thriller directed by Robert Zemeckis.

Pitt plays Canadian army officer Max Vartan, who goes undercover in Casablanca during World War Two, and pairs up with Cotillard's lively French spy Marianne Beausejour, to assassinate a German Nazi ambassador.

While the pair flawlessly play a happily wedded couple during their undercover stint, they soon find themselves falling in love for real.

But Marianne's alliances are called into question. 52-year-old Pitt has kept a relatively low profile since his split with Angelina Jolie was announced.
