British actor Warwick Davis has created a new smartphone app about celebrity culture.

The Harry Potter star worked on the PocketWarwick game for nine months and is hoping it will give users "an idea" of what life is like in the spotlight.

He tells Britain's Metro newspaper, "(On) my new phone game app, PocketWarwick... I'm a Z-list celebrity and you've got to get me on to the A-list. If you don't have enough money to feed me, the consequences are serious."

"I worked on it for nine months. People have said it's the weirdest game they've seen. I'm very proud of it. It gives an idea of what it's like to be an actor. The closer to the A-list you get, the better paid work you get."

"On the Z-list, you get offered work such as opening a launderette."
