The spot focuses on families getting together in Pizza Hut and enjoying the 'Four for All', which allows you to choose four of your favourite toppings so that the whole family can share one big pizza.
It also introduces Pizza Hut's new endline "Get Together" with the aim of encouraging families to spend a bit of quality time together over a meal out.
Wieden & Kennedy said that it was moving towards a more "naturalistic, observed tone of voice" with the 30 and 10 second ads, which portray a lively family discussion about what presents to buy for an elderly relative.
Hugh Wood, chief marketing officer at Pizza Hut UK, said: "With this commercial we wanted to focus on Pizza Hut's uniquely welcoming atmosphere as well as showing people that if you're having a hard time keeping everyone happy, Pizza Hut has the perfect solution."
Kim Papworth, creative director of W&K London, said: "With this campaign we wanted to get into a situation where we could show off both Pizza Hut's mouth-watering food and the relaxed atmosphere of their restaurants in a really natural, charming way that real families could identify with."
