It put me in mind of the 1991 TV movie, Never Forget, starring the late Leonard Nimoy as Mel Mermelstein, and directed by the late Joseph Sargent. Sargent, also director of the original Taking of Pelham One Two Three(which starred Martin Balsam), died a year ago tomorrow. So I bought a copy of the movie on Amazon’s video streaming service, which I haven’t seen since the 90s, and watched it.
In the movie, based on the actual story, Mel Mermelstein is a Holocaust survivor who has a small exhibit at his place of business, and goes to schools and other groups to talk about his experiences. He attracts attention from a Holocaust denying organization and feels the need to challenge them, despite the fact that most Jewish organizations tell him to simply ignore it and not give the hate group any further ammunition. There are people who consider Nimoy’s portrayal of Mermelstein to be one of, if not his best dramatic performances.
If you can afford it, I would recommend the Broadway musical Allegiance starring Star Trek actor George Takei. You’ll find the similarities between the Holocaust and the US internment camps for Japanese-Americans quite intriguing.
