Reality bit Tuesday for Lebanese film execs attending the Berlinale following news of an explosion just outside Beirut that killed at least three people.While majority of folk were chasing deals on their cell phones, members of the Lebanese delegation spent much of their time checking in on loved ones. “You feel like what you’re doing here is nonsense. It’s as if we’re in outer space but we have to continue. There’s no other choice,” said Beirut D.C.’s Hania Mroue, who’s part of Euromed group repping Arab and Lebanese films in the market. There was some good news, though. Helmer Faouzi Bensaidi’s “WWW: What a Wonderful World” has been sold to Denmark, while Mroue revealed a number of fest heads had been inquiring about holding Arab cinema spotlights.
