Forget James T. Kirk. William Shatner's crowning glory is Adam Cramer, a racist agitator who rides into a Deep South town during the days of racial integration and proceeds to stir up tensions within a white community who, at best, only grudgingly accepts such a concept.
Surprisingly, this uncompromising and hard-hitting issue drama was produced and directed by Roger Corman, the low-budget movie mogul more readily associated with horror and exploitation. His approach to the material has a lot of straightforward impact and it's frankly a shame that he never made another film like it. Shatner is also truly chilling as the charismatic firebrand who maliciously whips up discord and violence.
While the superficial details of American racial politics have metamorphosed since then, the same old prejudices still exist - as we have seen all too clearly of late. In that sense, The Intruder remains upsettingly relevant.
