You should read some books about Bat21 that movie is ok but very not accurate.
Here is a link to the real story:

I think there might be a book about it as well but there is not a really good doc on the whole thing.
A really good film about one of the few Vietnam era POWs to escape and later get rescued is Rescue Dawn about which is also a true story about a US Navy pilot that got shot down over Laos it is not 100% accurate either but is much better than BAT21 movie wise.
For some reason Panama gets ignored I think because starting not much later in 1990 began Desert Shield and then Desert Storm and they get more attention movie wise. But there was a little known Delta Force rescue mission during Just Cause called Operation Acid Gambit:
http://en.wikipedia.org/wiki/Operation_Acid_Gambit I saw a show about it on the Military channel once.A movie about the American (many claim CIA) Kurt Muse and then his rescue that could be a good film.
Another often unknown but outstanding operation from Vietnam is the Son Tay Raid:
http://www.psywarrior.com/sontay.html in many ways similar to the Osama raid and Operation Eagle Claw(history test
).The POWs where not in the camp during Son Toy but it did end up boosting morale of American POWs in North Vietnam and they where all moved into a handful of locations and where all together.
