Very enjoyable drama. Hellen is a stand out, as are the chimps.
Leonard Maltin/Plot synopsis:
Young military foul-up is assigned to top secret lab where he works with chimps--and soon becomes enraged at the tests they're being subjected to. Watchable but patently predictable story, with a finale vaguely reminiscent of a 1960s Disney comedy. The chimps (especially Willie, in the role of Virgil) are great, however.
