Grey’s Anatomy’s 7 biggest off-screen dramas: from Katherine Heigl’s Emmy’s beef with Shonda Rhimes, to Ellen Pompeo’s interview with Viola Davis – but who allegedly faked medical issues?

- The ABC show had some serious behind-the-scenes controversies, from director Denzel Washington going ‘ham’ on Ellen Pompeo, to Patrick Dempsey allegedly ‘terrorising the set’

Medical TV show Grey’s Anatomy made history on screen but also garnered headlines for behind-the-scenes drama … but which were the most scandalous? We’ve rounded up the most prominent controversies from 2005 to 2022.
