Should moviegoers expect a sequel to Mr. & Mrs. Smith?

Not quite – but Angelina Jolie and fiancé Brad Pitt are set to join forces on the big screen for the first time since they collaborated in that 2005 action film.

The new project will be based on a script penned by Jolie, PEOPLE confirms.

No word on the genre, release date, studio – or if their brood of six will make any cameos. Industry insiders speculate that it could be a relationship drama Jolie, 38, wrote several years ago, says the Hollywood Reporter.

Until then, Jolie is gearing up for the May 30 release of Disney’s Maleficent, while her film Unbroken – which she directed – is in post-production.
