New movies starring Colin Firth, Nicole Kidman and Kirsten Dunst will compete for the top honours at this year's Berlin International Film Festival with offerings from Iran, Tunisia the Philippines and elsewhere, with Meryl Streep presiding over the jury that will choose the winners.

Eighteen movies are in contention for the Golden Bear prize at the first of the year's major European film festivals. In its 66th edition this year, it runs Feb. 11-21. The typically diverse program was presented by organizers Tuesday.

The festival opens on Feb. 11 with the Coen brothers' Hail, Caesar! The star-studded cast includes George Clooney, Josh Brolin, Scarlett Johansson, Tilda Swinton, Ralph Fiennes, Jonah Hill and Channing Tatum, some of whom are expected in Berlin, where the comdy is screening out of competition.

It's hard to pin down any single overarching theme, but festival director Dieter Kosslick said many movies at this year's event address "the search for happiness" and "migration in the world in very varying forms."

The competition features two documentaries — Gianfranco Rosi's Fire at Sea, about the Italian island of Lampedusa, where many migrants arrive in Europe, and U.S. director Alex Gibney's Zero Days, on Internet surveillance.

Theater director Michael Grandage's movie debut Genius stars Firth, Kidman and Jude Law in a look at Max Perkins' time as book editor at Scribner, overseeing work by Thomas Wolfe and Ernest Hemingway among others. Also premiering in Berlin is Jeff Nichols' science-fiction thriller Midnight Special, featuring Dunst and Adam Driver.

Berlin prize-winners have been notoriously unpredictable over the years, with less prominent productions often picking up honours. This year's field includes an epic historical drama from the Philippines, Lav Diaz' A Lullaby to the Sorrowful Mystery, and the debut film from Tunisian director Mohamed Ben Attia, Hedi.

Last year's Golden Bear went to Iranian dissident filmmaker Jafar Panahi's Taxi, starring the director — who was officially banned from filmmaking — as a taxi driver.

This year's competition features two offerings from Iranian directors, though neither movie has such issues: Mani Haghighi's A Dragon Arrives! and Paris-based Rafi Pitts' Soy Nero.

A seven-member jury led by first-time festival juror Streep will announce the winners of the festival's Golden Bear and various Silver Bear awards on Feb. 20.
