Season 5 ofBig Brotherfeatured the Project DNA twist.
So, would the show ever go back to any of these crazy casting maneuvers?
We posed that question to Julie Chen Moonves.
“I don’t think I would repeat any of the twists,” says the host.
“I liked the exes twist.
That was season 4.
That was amazing, seeing people’s faces drop.”
We’ve had so many amazing twists and seasons and moments.
But those are hard to top."
Prepare yourself, people.
Oh, way to kill it!"
