(SPOT.ph) Going by the box office tallies of The Mistress and No Other Woman, it might be safe to say that A Secret Affair will also be a massive hit. Not only is it the latest in a string of infidelity flicks, it proudly wears its progenitors on its sleeve. The trailer voice-over proudly proclaims, "From the producer and stars of the box-office hit No Other Woman" (not 100% true; Cristine Reyes was swapped out for Andi Eigenmann). It even continues the aforementioned movie's proud tradition of panalo one-liners. The current staff favorite? Jackie Lou Blanco's "I faked every orgasm," viewable in the uncut version of the trailer below.

Also of note: Jaclyn Jose's "You're just a bitch. I'm the queen bitch."

But, as the cast and crew of A Secret Affair were at pains to point out during a recent press conference, this movie is different. "It's more modern," says director Nuel Naval. "It's more for the young." The cast and crew sit down with Spot.ph to dish on the secret affairs behind A Secret Affair.

On the sudden popularity of adultery movies

Writer Mel Del Rosario: I disagree na "nauso." Yung issue of infidelity at yung mga love triangles, di naman iyan nawala. If you review the filmography of Viva, mga time nina Hilda, nina Vilma, yung Kapag Puso'y Sinugatan, yungBaby Maker—there's something about "triangle" love stories that appeal to Pinoys. Siguro mas napansin kasi big hit yung No Other Woman and then yung The Mistress.

On their movie roles

Anne Curtis: I really, really love Andi's role here! I wanted to do her role! But in a way it was challenging for me to play the other character, because I'm so used to playing a gray character. To do something more tame was so hard for me to control! Certain nuances, just the simple flick of an eyebrow, changes your character altogether. But I enjoyed playing the goodie-goodie. Filming the ending was very hard for me, in a sense that you know you want to cry already, but Direk wanted it to be almost controlled. Siyempre you want to cry pero bawal magpatulo!

Derek Ramsay: The big difference between this movie and No Other Woman is that here I'm a bachelor. I'm not tied down. In No Other Woman I started off happily married, very much in love. Here, I start off [as a] playboy, one-night-stands here and there...let's call it casual sex. But he wants to say goodbye to that life, he wants to be tied down and be married, but the mistake he makes is that love is not enough. Men f*** up all the time.

Andi Eigenmann: It was hard and it was challenging, but that was part of the reason I accepted this role. Gusto kong mababad sa mga tao na makatulong para mas gumaling ako at sa project na mate-test ang perseverance atsaka hard work. It's really out of the box for me because I've never done anything closely like this.

On the movie's sexy scenes

Director Nuel Naval: In the film, I showed two kinds of love scenes. Anne and Derek's love scenes were very romantic, very sensual, full of love and passion. Yung isang kind naman is wild and raw. Yun yung kay Andi and Derek. They do it anywhere.

Derek Ramsay: That other kind wasn't a love scene. Like I said, it was a (whispers into the recorder) f***!
