As high-key dramatic as Greys Anatomy has been over the past 15 seasons (see: deer defibrillation, icicle-related violence, ghost sex, etc.), series star Ellen Pompeo is hinting that the real drama went down behind the scenes.

Pompeo, who is also a producer on the long-running ABC drama, spoke out about the really toxic work environment she experienced in the first decade of the series run in Varietys latest Actors on Actors conversation with Taraji P. Henson .

Henson asked Pompeo if there was ever a point where she wanted off this bus.

I never wanted off the bus in the year that I could get off, responded Pompeo, who recently extended her multimillion-dollar contract until Season 17. The first 10 years we had serious culture issues, very bad behavior, really toxic work environment.

Pompeo didnt elaborate on that statement directly, but the Emmy-winning drama has famously weathered its fair share of public scandals over the years be it actor Isaiah Washington using an anti-gay slur to describe his co-star T.R. Knight, or Katherine Heigl dropping out Emmy contention one season because she didnt think her material was good enough.
