How to make a dynamic main menu?

I am new to Unity and C#, but after a few weeks of learning, I'm getting kind of a hang of it. I want to make a "dynamic" main menu. Dynamic, in the sense that you would be able to see my main character moving in the background and when you would press "play" the main menu would disappear and the camera would zoom towards my main character and the game would start from there. It would be similar to LittleBigPlanet, but a little different. Thanks.
