The acclaimed new film Magpie was first conceptualized by Ridley, 32, and written by her husband and former Murder on the Orient Express costar Tom Bateman, 35. But the onscreen plot is nothing like their marriage, the Star Wars actress tells PEOPLE in an exclusive interview.

During a conversation held at the Dotdash Meredith offices in New York City Oct. 23, the British actress, 32, told PEOPLE's Senior Movies News Editor Nigel Smith that her husband, 35, is "in the know" about what her character Rey will experience in the next films.

Moviefone speaks with Daisy Ridley and Tom Bateman about 'Magpie'. I took the original idea to Tom, and he worked at layering all those things, Ridley said.
