Then Clash of the Titans, v2010, came up with some story of djinn who gave up their bodies for what looks like charcoal briquettes. Glowing blues eyes complete the cheesy effect. But this is Clash of the Titans - so cheesy is what it's all about. ;)
Actually, as characters, they are pretty decent. They help Perseus out and are instrumental in defeating Medusa. Most other movies give the djinn a nasty reputation for death and destruction. Maybe spelling it "djinn" versus "genie" has something to do with the creepy coefficient?
Then there's Wishmaster,1997. This guy just looks like Satan in a red cloak. What's up with the horns and claws? I suppose being evil entitles a djinn to whatever he wants, but... I'm not buying the look, even if it makes me wonder if my djinn need an image consulation. If I was an evil mastermind, I'd want to look pretty darn ordinary and let people think I was just like them, until I trapped them between a rock and a hard place. What do you think? What other djinn have you seen in the movies?
