There's no shortage of big reveals in "A Very Brady Renovation," but fans of the classic 1970s sitcom will be just as entranced by a smattering of blink-and-you'll-miss-it moments.
The HGTV special, which premieres on Monday at 9pm EST, is appropriately packed with those sweeping before-and-after shots we all know and love, and our jaw dropped along with those of the "Brady Bunch" cast during that first look at the iconic living room.
But as remarkable as the transformation is, it's just as fun to see the now-grown child stars reminisce about their Brady days. The first episode of the four-part special doesn't go too heavy on the storytelling, so you'll have to stay pretty tuned in to catch the best moments.
Upon first reuniting, the cast gets emotional realizing that it's their first time all together without Florence Henderson, Robert Reed and Ann B. Davis, with Eve Plumb holding back tears as the group gets their first look at the suburban house. Reed, who played dad Mike Brady, died in 1992 at 59 years old and Davis in 2014 at 88. Henderson passed more recently: She died in November 2016 at 82.

Most of the original cast reunited for "The Brady Bunch Variety Hour," which launched after the original series wrapped. Missing was Eve Plumb, who didn't want to commit to the contract. She was replaced by Geri Reischl, who fans quickly dubbed "Fake Jan."

Robbie Rist was introduced in the final season of "The Brady Bunch" as Cousin Oliver. Producers hoped that adding a child would restore some of the youthfulness of the earlier seasons.

The Brady kids handpicked rooms that felt most special to them. Susan Olsen, who played Cindy, remained very close with Davis in the decades following the show, which is why she's tasked with restoring Alice's bedroom — which was only fleetingly shown once or twice in all of the show's five seasons. There isn't too much time spent on this in the premiere, so you'll have to watch closely to see certain cast reactions to different rooms of the house.
Brady fans from around the world helped contribute vintage lookalike items to the house. Re-discovering certain elements of the home proved incredibly difficult, so HGTV turned to an open call for fans who might be willing to contribute their own possessions. That's how a number of hard-to-find decor items found their way into the home.
More unexpected guest appearances are definitely in store. AOL already knows of one famous face who's slated to appear in the bonus Christmas episode (no spoilers!), but we're willing to bet we'll see some more special guests in the episodes following the premiere. There might even be a bit of foreshadowing in the premiere itself.
