In Raider of the Lost Arc we had snakes.

In Temple of Doom we had nasty, crunchy bugs.

In The Last Crusade we had rats.

What's going to be the creature in Kingdom of the Crystal Skull?

So Indiana Jones 4 is in production, and, of course, needs a name. So LucasFilm has registered the following titles as the possible picks for the new Indiana Jones movie. (Although personally I don't think any title can be as good as "Raiders of the Lost Ark.")

So here are the names that were registered. And it should be noted that the final film title may not even be one of these. In fact, these all may be red herrings. So take them with that proverbial grain of sand.

• Indiana Jones and the City of Gods
• Indiana Jones and the Destroyer of Worlds
