Quick Look: Toy Soliders (1991)

This is a somewhat overlooked decent little action film from the early 90's starring Sean Astin, Wil Wheaton, and Louis Gossestt, Jr.  The bulk of the movie takes place at a private boys boarding school called the Regis School, where the main characters are the students.  The boys are all from rich, influential families, and many of them have been kicked out of multiple other private schools for discipline problems.
A group of Colombian terrorists led by Andrew Divoff take over the school to kidnap a judge's son to force the judge to release Divoff's father who is currently in custody.  Explosions and gunfire pave the way for excitement as the terrorists are taken down, but not without losses for the good guys.  The FBI and the Army show up, but it is ultimately the boys defiantly rising up against their powerful captors that wins the day.
The movie is fairly predictable, and has a typical "underdogs vs. ____ " tone to it.  You will have to reach a little with the believability factor, but the action sequences and acting of the students keeps it entertaining.  Plus it is always fun to go back and see Wil Wheaton and Sean Astin in the early parts of their careers.  It's worth an afternoon viewing.  'R' rating is for violence and language.
