Methinks I see a pattern...
  1. Ava DuVernay (Middle Of Nowhere, Selma)
    Turned down Black Panther, as of today.
  2. Joss Whedon (Buffy The Vampire Slayer, The Avengers)
    Turned down Infinity something or other after creative differences on The Avengers 2.
  3. Edgar Wright (Shaun Of The Dead, Scott Pilgrim)
    Left Ant-Man over creative differences.
  4. Adam McKay (Step Brothers)
    Turned down Ant-Man.
  5. Michelle McLaren (Game Of Thrones)
    Turned down Wonder Woman.
  6. Kenneth Branagh (Much Ado About Nothing, Thor)
    Turned down Thor 2.
  7. Patty Jenkins (Monster, The Killing)
    Left Thor 2 over creative differences, now onboard for Wonder Woman...we'll see where that goes.
