Spielberg "is blacklisted by the Arab League's boycott office, which Lebanon complies with," the official explained.
The pan-Arab body maintains a regional boycott of Israel, and blacklisted Spielberg after he donated

and Bridge of Spies
were shown in the country.
Opponents of censorship decried the decision as an attack on free speech in a country known for its relatively liberal values in the region.

The censorship axe also hit Jungle
, a survival drama about Israeli adventurer Yossi Ghinsberg, who got lost in an uncharted part of the Bolivian Amazon in 1981.
Last year, Lebanon banned Hollywood blockbuster Wonder Woman
because lead actress Gal Gadot had served in Israel's military.
