Alec Baldwin has been tapped to return as the host of the Hamptons Intl. Film Festival’s SummerDocs series, which has lined up “Buck” and “Page One: A Year Inside the New York Times” for two of its four offerings.

Although Baldwin will host most of the screenings, James Lipton is on board for the series’ launch film, horse whisperer docu “Buck,” set to screen June 4 ahead of its June 17 release from Sundance Selects.

Baldwin will host the July 22 screening of Magnolia Pictures’ “Page One,” in an event that will include a discussion with helmer Andrew Rossi and others involved in the pic.

Two more screenings in the doc series are set for Aug. 19 and Sept. 1, but the films remain to be nailed down.

SummerDocs is one of the run-up events to the annual Hamptons fest, this year set for Oct. 13-17.
