|Jawdroppers. Zachery Ty Bryan and Kirsten Dunst|
Dunst plays one of two siblings lost in the Alaskan wilderness. She and the other kid (Zachery Ty Bryan) let their lower jaw drop in moments of dramatic suspense. Now that I think about it, they both use that trick to express a broad array of emotions, from happiness to frustration to befuddlement to surprise at falling backward over a cliff.
As actors, they give their jaws a pretty good workout.
