He arrived without paparazzi or even a social media announcement. But actor and author BJ Novak – best known for playing Ryan Howard on the American version of The Office – has been spotted around Jerusalem this week. The reason for his visit remains a mystery. Novak has been in the country since at least Friday, when he posted on his Instagram story – which disappears in 24 hours – a photo from McDonalds. Novak, who grew up in a Jewish family in Massachusetts and attended a Solomon Schechter Day School, hasn't posted much about his trip. But that didn't stopped him from being seen on Monday. First, tour guide Gal Abdu posted a photo of himself and Novak overlooking the Old City of Jerusalem. “My guest today was a world-known actor, and I didn't know him,” wrote Abdu. “Well, a super exciting tour anyway. Loved it!” My guest today was a world known actor, and I didn't know him Well, a super exciting tour Anyway, Loved it! . . . . . . . . . . . #bjnovak #bjnovack #theoffice #netflix #celebrityinisrael #jerusalem #moviestar #hollywood #picturesoftext #vip #viptour #tourguideinIsrael #jews #jerusalemoldcity #templemount @picturesoftext A post shared by Gal Abdu - גל עבדו (@galabdu) on Apr 9, 2018 at 7:42am PDT Later that night, Novak stopped by the popular kosher eatery Crave in Mahaneh Yehuda. The restaurant posted a photo on Instagram and Facebook of the actor posting with co-owner James Oppenheim.
