Dust off your cufflinks and put on your best dancing shoes, because Royal Pains' Evan (Paulo Costanzo) and Paige (Brooke D'Orsay) are getting hitched! "When we first wrote Paige Collins into the show, we never foresaw that it would end up the way that it did," executive producer Michael Rauch tells TVGuide.com of the special two-hour movie, airing Sunday at 9/8c on USA. "The more we told the story with them together, the more we realized this was the love story of the series so far." So what's in store for the couple on their big day? We talked to Rauch and co-creator and executive producer Andrew Lenchewski about what to expect:
1. Baby, it's cold outside! For the first time in Royal Pains' four-year run, viewers will get to see the Hamptons in the wintertime. "We've always talked creatively about the exciting possibilities of showing the Hamptons with its very different but still very real beauty during the winter with the snow falling and the place being a little bit more empty," Lenchewski says. However, because the episodes were shot back in September, "we spent a great deal of time in post-production removing beautiful grass and leaves on the trees and adding snow," Rauch adds.
2. Inspired by a true story. Thanks in part to the rough winter weather, expect everything that could go wrong to go wrong for Evan and Paige on their big day. "There's one obstacle after another before they walk down the aisle," Lenchewski says. Their woes are based on his own wedding, which took place in the midst of Hurricane Irene last August. "I wasn't personally dying to relive the experience anytime soon, but the writers insisted," he says. "The truth is, it's a very fitting story to tell for Evan and Paige and capping off their very unpredictable courtship."
3. What happens in Vegas, doesn't always stay in Vegas. Before the wedding, expect to see one heck of a bachelor party for Evan, which takes place on location in Sin City. "Vegas was our partner in putting this together and they really helped open a lot of doors so we could actually get on the casino floor, which is a rare opportunity for TV shows and movies," Lenchewski says. Also look for shots inside one of the Palms suites and in front of the Bellagio's famed fountain show.
4. Meet the (extended) family. The wedding will also introduce Evan and Hank's cousin Owen (Charley Koontz), but it won't exactly be a happy family reunion. "In the movie, Evan discovers that that he completely blocked out the fact that Owen had given him money to invest and Evan had lost a lot of that money," Rauch says. "Evan feels really bad and he suddenly feels he needs to repay Owen to redeem himself. As a result, he's feeling the pressure of all this money that's being spent on the wedding. ... Should this money be spent on the wedding or helping cousin Owen?
5. Guess who's back? After packing up and heading to Africa early in Season 4, Jill Casey (Jill Flint) will pop up. "As soon as she left, we had fans already beginning to clamor for her return and we just wanted to pick our moment very carefully," Lenchewski says. "We talked a little bit about the possibility of the character returning in the summer finale, but it ultimately felt like a better surprise to bring her back in the movie."
6. A blast from Hank's past. It may be Evan and Paige's big day, but the movie will also devote time to Hank's love life, in flashbacks introducing Winnie (Emma Caulfield), the childhood love he left behind. "We realized what a powerful opportunity it could be to show who our characters were before, since we joined them at such a specific point in their lives," Lenchewski says. "We didn't ever really establish a sense of who they had been beforehand." The flashbacks will also shed some light on why Hank has had such trouble with the ladies. "We felt like this would be an opportunity to actually go back and see where maybe some of these problems stem from," Rauch says. "For us, that came from this love that he let get away when he made the wrong choice to leave his great love behind because of the woman he then got engaged to."
7. The doctor becomes the patient. Spoiler alert! Hank (Mark Feuerstein) survived the explosion at Shadow Pond that occurred in the Season 4 finale. However, he'll still be reeling from the aftereffects of the trauma. "It felt like a natural way to progress a physical manifestation of the Boris explosion without having to wrap that story line up," Rauch says, "to finally let the doctor who's always helping other people get help himself."
8. Hold the phone! After Rafa broke her heart, Divya (Reshma Shetty) is not in the best place when the wedding rolls around. Look for her to do something truly shocking. "We loved that this [Rafa] story line showed this spontaneous, impulsive, unexpected side of her that maybe she didn't even know existed," Lenchewski says. "It felt like the perfect opportunity to culminate all of that." Adds Rauch: "In our minds, this is going to be the most controversial moment in the movie. ... It was for us too in the writers' room. We spent a lot of time talking about the pros and cons of it, and how it fit into the character of Divya. Ultimately, it felt like it worked."
