Sagot niya, “I’m acting and the viewers are smart enough to know that that’s what we’re doing.”
Nabanggit din niya na parang nauuso ngayon ang mga pelikulang tumatalakay sa extra-marital affairs.
“Lahat nga ng pelikula parang [tungkol sa] affair, e, 'no?
“But I think that’s what people want to see because a lot of people can relate.
"It does happen in real life, sad to say.”
Nang binasa raw ni Derek ang script ng A Secret Affair ay nagustuhan niya ito agad.
Sinabi niya raw sa kanyang sarili: “I’m going to do it and I’m here to do it to the best of my capabilities.”
Hindi rin daw siya nag-aalalang ma-typecast na "playboy."
Paliwanag ni Derek, “I don’t think anyone’s going to typecast me as a playboy in real life.
"I already am, I think.
“There’s nothing I can do about that. I’ve had that problem since high school.
"But like I said, it doesn’t affect me.
“I’m here to do my work and hopefully it gets success as No Other Woman and Praybeyt Benjamin.
“Bonus na yun if we surpass that. We’re here to do a good film.”
Ang No Other Woman at Praybeyt Benjamin ang dalawa sa biggest hits sa takilya noong isang taon, at masuwerteng kasama si Derek sa parehong pelikula.
