Starring Michael Fassbender and Cate Blanchett, 'Black Bag' is a thriller that director Steven Soderbergh says takes influences from classic cinema.

“ Black Bag ,” an elegant, quick-witted new thriller that finds Cate Blanchett and Michael Fassbender playing married spies, isn’t the pair’s first time together on screen. That honor goes to 2017’s “Song to Song,” one of Terrence Malick’s most intangible and head-scratching offerings — though the two stars can barely recall that experience.

Michael Fassbender cannot lie — the polygraph scene in Black Bag was a bear for him to shoot.
