David Niven of course reached the high point of his career with his Best Actor Oscar for Separate Tables, where he played a blowhard "major' who was a permanent guest at Wendy Hiller's establishment. 18 years later he kind of revives that character when he takes a job as a tutor for Toshiro Mifune's little boy Ando in Paper Tiger.
Like in Separate Tables Niven puts on a great front about his great war exploits which is all a front to hide a deeply flawed man. Here he's doing the same thing for Ando. Mifune is the Japanese ambassador to some Asian island country, not named but I'm guessing Sri Lanka because there is a reference to a Tamil minority that is a rebel faction.
Anyway these rebels or at least this cell of them led by Irene Tsu decide to kidnap the Japanese Ambassador's son to call attention to their prisoners. As we've seen many times, mostly in the Middle East, they'll kill the kid and Niven who was with him at the time unless their comrades are released from prison.
Niven who also appropriates the rank of major in this film as well is actually forced to become the hero he's told Ando he was. He never got that chance in Separate Tables.
I think this might have been aimed at the kiddie market, but it's way too bloody and violent for that. Niven already did that with Please Don't Eat The Daisies and he would do a couple of films for Disney Studios which were certainly better suited than Paper Tiger.
Still it's decently entertaining, but not for the little ones.
