Undercover Grandpa

A Spy Kids genre movie where James Caan plays senile grandpa who is always telling crazy stories about how he invented dark chocolate or single-handedly stopped the Russians from taking Berlin after WWII. When his grandkid's wannabe girlfriend (crush?) is kidnapped by an escaped South American warlord (see how silly this is already), Caan re-activiates his old unit of now geriatric special forces. The 4 of them, plus the two teenagers, take on and take out a cadre of mercenaries with more guns than the entire force of Mr. Smith in the Matrix.
