Travelogue "Royal London" then bows on April 27, followed later that day by the two-part "How to Be a Prince," focusing on William's past, present and future.
BBC America will also mix in several interstitials, such as "Graham Norton's Royalty Checks" and "Katy Brand's Royal Family," offering commentary on the wedding preparations in the U.K.
Most prominent among BBC America's earlier royal wedding programming announcements was two-part special "Royally Mad," in which Cat Deeley acts as London tour guide for a quartet of American royal wedding fanatics. That airs April 12 and 19.
