Guessing saw the movie sometime in the 90’s.  I “think” Tommy Lee Jones was in it as the good guy. I’ll use him throughout as reference, though it may have been another well-known actor.  He was after a person or group of bad guys, possibly terrorists or drug cartel.  I believe the child may have seen something the bad guys did.  While in the care of a female (she was a doctor/social worker type person) and Tommy Lee Jones, the child tries to ‘hide’ in plain sight by using paints and dyes to paint his body to blend in with the surroundings.

One scene in particular I remember is Tommy, the child, and the woman were in a big room with high ceilings, tall windows, and tapestry-like curtains.  Looking at the room, you don’t see the child.  But then Tommy sees the child standing on the window sill against the curtain and is perfectly camouflaged to blend right into the curtain pattern.  I remember Tommy saying something to the effect that the child was part of tribe x (I think from the Amazon region) who were well-known for their body camouflage technique.

I would love to see that movie again because of my fascination with the tribal camouflage technique and what was the name of that tribe.  Any help appreciated – thanks!
