BBC America’s royal wedding march gained a few more drummers with the announcement of several more programs leading up to the April 29 marriage of William and Kate.

First of the new crop is “Prince William & Prince Harry: Into the Future,” a March 22 special that looks at the world of the princes and their circle of friends. That will be followed a week later by the previously announced “Modern Monarchy: Dos and Don’ts.”

A bevy of recent BBC America doc acquisitions have been scheduled for the week of the wedding, starting with “Diana’s Dresses” and “Princess Diana — Her Life in Jewels,” airing back-to-back April 24.

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 (“So You Think You Can Dance”) acts as London tour guide for a quartet of American royal wedding fanatics. That airs April 12 and 19.
