Jamie Dornan is about to plunge into another complicated romance.

The "Fifty Shades of Grey" star and Holliday Grainger ("Animals," "Patrick Melrose") are set to play star-crossed lovers in "Wild Mountain Thyme." The project is from John Patrick Shanley, who is adapting his hit Broadway stage play "Outside Mullingar."

The couple is torn apart by their families, who are caught up in a feud over a hotly contested patch of land that separates their two farms.

Shanley is a Pulitzer- and Tony-winning playwright whose work includes "Doubt" and "Moonstruck."

Filming on "Wild Mountain Thyme" will begin this summer in Ireland and New York. The eponymous song (covered most recently by Ed Sheeran) will be featured.

Dornan has kept busy since the end of the "Grey" franchise, appearing last year in "A Private War," "Robin Hood," and "My Dinner With Hervé."
