Organisers unveiled a programme packed full of strong independent and arthouse productions on Thursday, but lacking major Hollywood studio support -- a pattern seen at other European festivals this year.A total of 20 films will compete for the prestigious Golden Lion top award over the September 2-12 festival, including "Primetime" by Lance Oppenheim about an American TV show that sought to expose paedophiles. It stars Pattinson, fresh from his acclaimed performance as the villainous Antinous in current box-office champion "The Odyssey"."This film is the true story of the unscrupulous host of a disturbing reality show by NBC," Venice festival director Alberto Barbera told reporters about "Primetime".Other in-competition highlights include "Wild Horse Nine", a dark comedy by Ireland's Martin McDonagh starring John Malkovich and Sam Rockwell, as well as "Bunker" by Florian Zeller featuring real-life Spanish power couple Javier Bardem and Penelope Cruz.As previously announced, the competition will open with "Ink", a film about press baron Rupert Murdoch's transformation of the British media by "Trainspotting" director Danny Boyle.The latest movie from German veteran Werner Herzog -- "Bucking Fastard", featuring sisters Kate Mara and Rooney Mara -- will also be in the running for the Golden Lion.Two of Asia's most acclaimed filmmakers, Japan's Hirokazu Koreeda ("Shoplifters") and South Korea's Lee Chang-dong ("Burning"), are also in the line-up.Hollywood ghostingHollywood and US streaming giants Netflix and Amazon chose Venice to host a series of big-budget films last year, but they have mostly steered clear this year.European festivals typically rely on Hollywood to provide a dose of mass-market entertainment alongside the sometimes edgy independent cinema that forms the core of their programmes.
