Tom Hanks, whose Playtone company is one of this fine documentary series’ production partners, appears on camera in tonight’s episode – and, since Hanks so memorably proved he had the right stuff by portraying astronaut Jim Lovell in 1995’s Apollo 13, he’s more than earned the right to put the Space Race, which both predated and outlasted the Sixties by a few years each way, in his own entertaining perspective. But he’s far from the only one on tap tonight – and, as usual with The Sixties, vintage television footage emerges as the best storyteller of all.
