Shirley Jones!

She produced the fantastic Big Brother 5, with the evil theme and all. But perhaps her biggest accomplishment was rebounding from the least watched Series, BB10, at 2.3million with Celebrity Big Brother 7, launching with 6.7million and averaging 3.7 million. The most watched series since 2007.

If she could rebound from the disaster that was Big Brother 10 (excluding a mostly fantastic cast of housemates), perhaps she's the only person who has the skills to make Channel 5 Big Brother a success.
