Before a cheating scandal rocked the lives of both Kristen Stewart and Rupert Sanders, the pair spent months together on the sets of Snow White and the Huntsman.

While filming SWATH, Sanders, 41, seemed infatuated with Stewart, 22, but it never went any further, a source tells PEOPLE. One of the reasons could be that Sanders’s wife, actress-model Liberty Ross, starred alongside Stewart in the film, playing Snow White’s mother. Sanders even cast the couple’s two children, Skyla, 7, and Tennyson, 5, as extras in the film’s final scene.

But a photo unearthed from May shows Stewart and Sanders enjoying dinner with a small group, which included fellow castmember Charlize Theron, at Berlin’s Monsieur Vuong Vietnamese restaurant.
