Wgtd's The Morning Show With Greg Berg

This interview is a preview of a superb three-part documentary titled "Chasing the Moon" that airs next week (July 8, 9 and 10) on the PBS series American Experience to commemorate the 50th anniversary of Apollo 11 landing on the moon.    My guest is Robert Stone,  an Academy Award nominee, who both directed and produced the film.  Stone calls this the biggest undertaking of his career - and 25 years in the making.
