An old movie from the 80s that has got my interest recently from seeing reviews or discussions on is Bat*21.
A Vietnam War movie based on the real life rescue of Lt. Col. Iceal Hambleton.
Hambleton an important person in the American military hadn't seen any combat was shot down and had to survive in the jungle as the Viet Cong listened to their radio transmissions and attempted to hunt him down. He's guided by guys circling in planes.
The movie stars Gene Hackman as Hambleton and also stars Danny Glover as the pilot that helps him through.
Details on the rescue.
The movie is actually on YouTube. Seen one video is an hour 20 and another is an hour 40. The official runtime is 105 minutes.
Here is the trailer. I do miss the older trailer with the voice over guy talking over the plot instead of just clips.
