Andy Baio writes about the leaking of a Secret Life of Walter Mitty screener from the offices of The Ellen Show:

Oh, Ellen! If the watermark's accurate, this screener belonged to Ellen DeGeneres. But was it actually an Oscar screener? Probably not.
The watermark shows that the screener was created on November 26, 2013. According to Ken Rudolph's Academy screener list, he received the Walter Mitty DVD screener via UPS on December 19.

This is one of the most inopportunely timed and high-profile leaks of a secure screener. That this has gone lightly reported (and treated as anything but a controversy) is telling of either the stature of DeGeneres in the industry, or the lousy reviews of Mitty.
