The surviving members of the Grateful Dead are present and accounted for in the Martin Scorsese-produced documentary “Long Strange Trip,” but with a running time of four hours, you’d think there would be commentary from Bob Dylan or, at least, John Mayer. No dice. Instead, the tale is largely left up to roadies and managers, not exactly star-studded company for such a challenging haul.

New kid on the block
All eyes will be on NBC’s newly acquired heavyweight with the launch of “Sunday Night With Megyn Kelly,” a test drive before she enters the competitive circuit of morning news.

The Chicago way
“Andrew Santino: Home-Field Advantage” finds the rising stand-up star exploring well-worn territory as he returns to his Chi-town roots. But Santino is someone to watch, perhaps more as an actor than a comedian.

For more on that series, see Sunday’s Variety section.
