Leon Ford’s Australian superhero comedy “Griff the Invisible,” starring Ryan Kwanten (“True Blood”), and Norwegian director Anne Sewitsky’s “Totally True Love” will open the Berlinale’s Generation children and youth sidebar.“Griff,” which kicks off the older-skewed Generation 14plus, is about a young office worker who dons a superhero costume by night to fight crime but ends up falling for his equally quirky neighbor. Ford, Kwanten and co-star Maeve Dermody (“Beautiful Kate”) will attend the Feb. 11 premiere. Jan Chapman, who exec produced “Griff,” is serving on the Berlinale’s international jury for the main competition section. Opening Generation Kplus on the same day with its world premiere, “Totally True Love” is a racy drama about first love that focuses on a 10-year-old girl whose major crush not only triggers butterflies in her tummy but also intense jealousy and a thirst for revenge. In a special screening, Generation is honoring Tim Pritchard’s British-South African documentary “Street Kids United,” featuring aid project Umthombo, which helps street children. Pic follows a kids’ soccer team to the 2010 Street Child World Cup in Durban. The filmmaker and members of the soccer team will attend the Feb. 17 screening.Meanwhile, Generation is cooperating with other Berlinale sections to make a wide range of films accessible to viewers under age 18 as so many works from around the world are increasingly focusing on coming-of-age stories. This year’s cross-section screeners include Victoria Mahoney’s U.S. competition film “Yelling to the Sky”; French director Celine Sciamma’s Panorama title “Tomboy”; and, from the Forum section, Richard Ayoade’s U.K. drama “Submarine.” As part of the fest’s Culinary Cinema, the German documentary “Taste the Waste,” a disturbing look at how food is wasted worldwide, will also screen for the public. In addition, in collaboration with the Retrospective, Ingmar Bergman’s 1982 classic “Fanny and Alexander” will be screened for school children as part of an educational presentation hosted by a film expert. This year’s Generation films will screen at a new venue, the 1,000-seat cinema at the House of World Cultures, which offers one of the city’s biggest auditoriums. The Berlinale runs Feb. 10-20.
