Golden Anniversaries honors director Peter Bogdanovich — who, like Sidney Poitier, died on Jan. 6 — with a discussion of the screwball comedy "What's Up, Doc?," his polar-opposite follow-up to the elegiac "The Last Picture Show." On a trip to San Francisco to compete for a music grant, a young researcher (Ryan O'Neal) meets a zany college dropout (Barbra Streisand), and their antic, contentious relationship further adds to the multiplying complications when four identical plaid bags and their valuable contents all end up in the hands of the wrong owners. The stellar comedy cast includes Madeline Kahn, Kenneth Mars, and Austin Pendleton, and the script — which channels Howard Hawks' classic "Bringing Up Baby" — is co-written by Buck Henry ("The Graduate") and the team of Robert Benton and David Newman ("Bonnie & Clyde").
