Knock Knock Live

Knock Knock Live is an American reality television series starring Ryan Seacrest that debuted on Fox as an entry in the 2015–16 television season. It premiered on Tuesday, July 21, 2015 live at 9pm ET, tape delayed at 9pm PT.

In the show, Seacrest and guest celebrities would visit the homes of ordinary people who have done something special and give them a prize such as cash or a new car. Some would meet their celebrity crushes, or a random game would take place in their front yard or on their street. Seacrest said: "We've tailored all of our responses to hopefully put a smile on people's faces and change their life a little bit. The fun thing about it, for me, is that this is a live show, so we don't have an idea of what's gonna happen."

On July 30, 2015, Fox canceled the show after two episodes due to low ratings.
