Towards the end of the film, reference is made to a Piper Cub aircraft being used for spotting/reconnaissance. The original Piper Cub was manufactured from 1938-1947. In military configuration, from 1943-1946, it was officially known as the L-4 "Grasshopper" (since it was painted Army Olive drab), but most soldiers still called them "Cubs." There were actually over 5,400 produced for the US military during that time.
This is one of a handful of Metro-Goldwyn-Mayer productions of the 1950-1951 period whose original copyrights were never renewed and are now apparently in Public Domain; for this reason this title is now offered, often in very inferior copies, at bargain prices, by numerous VHS and DVD distributors who do not normally handle copyrighted or Metro-Goldwyn-Mayer material.
The network television premiere was in 1979 on CBS, 28 years after premiering in theaters, possibly the longest interlude between theaters and television of any major movie since the advent of national broadcast television.
Even though the 442nd Regimental Combat Team is the most decorated unit in US Army history, there is only one brief--VERY brief--scene of President Harry S. Truman pinning a medal on a soldier's chest, with no ceremony or dialogue. There is also an earlier reference, almost a throwaway line, by Lt. Grayson (Van Johnson) about awarding a soldier a medal.
