Pablo Schreiber gave up on keeping secrets long ago.
As a 12-year-old boy, he attended a sleep-away summer camp with his 14-year-old sister. Like any young fellow on the verge of puberty, he found a pretty girl.
“I told this girl who I was interested in that I was actually 16,” he recalls to The Post. “I think she was buying my story and it was leading up to the place where I was maybe going to get to take her into the forest and have a little kiss or make out or something.”
No go.
“[At] the dance at the end of summer camp, my sister told this girl I was seeing that I was only 12,” he says. “It broke my heart. From that point on, there were no secrets.”
Secrets cause trouble left and right in his new movie, “After,” in theaters Friday. In the family drama, Schreiber plays the son struggling to keep the family business afloat amid siblings and parents, all with their own neuroses and problems.
Schreiber, 36, is no stranger to family drama. He’s currently separating from his wife, with whom he shares 5- and 2-year-old children.
“I have an interesting relationship right now in my life with transparency and honesty,” he says, seemingly alluding to the situation. “I’m going through a period of my life where the need to be honest has trumped everything else in my life.”
Schreiber’s been finding truth in acting for years, emerging from the shadow of his half-brother, actor Liev, with notable stints on shows such as “The Wire.” But nothing has compared to the attention he’s garnered as “Pornstache” on “Orange Is the New Black.”
Last summer, his career reached new heights when the show debuted on Netflix. His character — the villainous yet hysterical corrections officer Mendez — was given the “Pornstache” moniker for his larger-than-life facial hair. He returned in the second season for a limited arc, due to his casting on the now-canceled “Ironside” remake.
“I was disappointed to not get to take part in it as much,” says Schreiber, who resides in LA. “[But] the stuff they wrote for me ended up being fantastic.”
That short stint may be the last we see of Mendez. Schreiber’s now booked on his new HBO comedy, “The Brink,” opposite Jack Black and Tim Robbins.
“I’m not taking part in the third season [of ‘OITNB’],” says Schreiber, noting it was his decision. “[The new] show was a better move.”
And he won’t miss the ’stache: “Given how iconic that character has become,” he says, “I am unlikely to sport a mustache as a fashion accessory.”
