TV on DVD: 'Marcus Welby' and Tracey Ullman

MARCUS WELBY, M.D.Series Top-rated show of 1970 stars "Father Knows Best" dad Robert Young as a crusading Santa Monica family physician, aided by James Brolin's young doctor who takes house calls on a motorcycle. (House calls?) It's a surprisingly effective what's-what of social issues and medical advances. Plus, it's a who's-who of guest stars - newcomers like Richard Thomas, David Cassidy; veterans like Anne Baxter, Vera Miles. And 23-year-old Steven Spielberg directed one episode (but not very well).

Extras Pilot TV movie, episode guide booklet.
