No, not free, but you can buy it. I got mine for 4 bucks!
There is no demo.
For Lego Harry Potter, there is no PC demo.
i don't believe that there is a demo in PC only in xbox 360
The PC Demo lasts 5 in-game days (1 hour 20 mins) and the PC full version lasts forever
If I remember correctly, all you need is PC, Mirror's Edge game for it and some cheats. But I don't recommend. Game is much better in 1st person view.
There is no demo on the PC
Not at the moment, there will be a demo on the PC, possibly not the 360
No there was not ever a demo for the game
