The  low-budget, made-for-TV thriller, Last Best Chance, has an unusual origin, explained in Big Guns Try to Peddle A Nuclear-Terror Film:
The movie was the brainchild of Mr. Nunn, who has spent years pushing to keep nuclear arms from falling into the wrong hands. Even in the wake of the Sept. 11, 2001, terror attacks, he feared the government was moving too slowly to address the threat while the public was largely inured to it.So Mr. Nunn, who isn’t known for his left-coast sensibilities, decided to go Hollywood. He persuaded the bipartisan board of his advocacy group, the Nuclear Threat Initiative — which he co-heads with Mr. Turner — to spend $1 million on a made-for-TV movie dramatizing the clear and present danger of nuclear terrorism.
