And that’s just the American TV hosts.

Ha, ha, we kid. Sort of. There will be cameras positioned inside St. George's Chapel to televise and livestream the hotly anticipated nuptials between the Queen's roguish redheaded grandson and his American actress beloved. And U.S. broadcast and cable networks are taking full advantage of it. (And not just them. Earlier this week, Fathom Events announced it will show the wedding and festivities commercial-free and almost live at select movie theaters around the country.)

The wedding ceremony is scheduled for 7 a.m. EDT (noon in the United Kingdom). Most networks are planning at least five hours of live coverage starting as early as 5 a.m. on the big day.

That's all?!

Hardly.

From more dignified PBS specials to a brand new Lifetime movie featuring Harry and Meghan “lookalikes” (you be the judge), there’ll be gobs of royal wedding-related programming in the days leading up to the ceremony. It won’t even end with the “I do’s” as there will be replays and more specials for hours afterwards.

Here’s your royal wedding viewing guide. It will continue to be updated with late breaking programming information.
