What are the laws regarding Making a fan Game of a Movie?

What happens if someone make a , for example, a little star wars game, like Star wars 1 pc (1999) but with mp capabilities? I mean, for free and no $$$$ involved.

Is that a crime ? I saw that sega sued some guys that made a re-make of street of rage 2… But sega is dumb. so Yeah :stuck_out_tongue:
