Actor/producer Ashton Kutcher has turned his new reality game show Opportunity Knocks into a way for his family — wife, actress Demi Moore, 45, and stepdaughters Rumer Glenn, 19, Scout LaRue, 17 on Sunday, and Tallulah Belle, 14 — to grow closer. The 30-year-old admitted that when he started thinking about concepts for the series, which features host JD Roth showing up at a family’s home and creating a game show on their front lawn, that he began "playing with that idea with my family and with my girls" asking questions like, "Who is Tallulah’s favorite band?" or "What kind of perfume does my wife wear every day?"

Opportunity Knocks premieres on ABC on Tuesday, September 23rd at 8 p.m. Rumer, Scout and Tallulah’s dad is actor Bruce Willis.
