I remember watching this movie back in Russia between 1998-2003. It was definitely a Hollywood movie dubbed russian. It was in color and I believe the plot went like this:

Two men and a woman were looking for a treasure in a jungle/forest. They fell  into some sort of tunnel/slide that was some sort of shortcut and they landed some other place where they were captured by indigenous people. They are brought to the village and the tribe makes them enter a place where is lying down a beautiful woman (their queen? a princess?). She wore some sort of a headpiece full of jewels and the scene when the friends see her, she’s lying like a doll, in those jewels.
Later on in the movie, I believe she marries one of the guys, then they escape with her and the village is on fire.

At the end of the movie, they’re back to their home and we see them getting on a hot air balloon and happy.

thank you for your help
