A few points

Rating: 10/10 (24 May 2012)

Although Stempel did follow orders and miss the question about "Marty," the question that eliminated him was a three-parter about a famous editorial. He was told to answer the first two parts: the paper was the Emporia (Kansas) Gazette, the editor was William Allen White; then he would "blank" on the name of the editorial: "What's The Matter With Kansas?" Ironically, his history class at CCNY had talked about the editorial just a few days earlier.
Rob Morrow is actually, as far as I'm concerned, the worst actor in the movie. He can't make up his mind if he should adopt a Kennedyesque accent or sound like Peter Falk as Columbo.
Finally, although Charles Van Doren wrote an article about "Twenty-One" in 2008, the first he'd said publicly about it since the hearings in 1959, he added nothing new. On the other hand, this movie brought Herb Stempel back into the spotlight and, despite what he did, I think the public now looks on him as the good guy in his encounters with Van Doren. And by the way, he doesn't look nearly as nerdy as he looked when he appeared on the show or as John Turturro played him; Dan Enright was trying to create the image of a nerd and Robert Redford obviously followed suit for authenticity's sake.
