The 930-mile trip took over 15 hours. Whitney Houston hit the high seas to get to Dublin for the next stop in her world tour. The singer and her entourage took a 3 hour, 15 minute car ferry across the Irish Sea from Holyhead, Wales to Dublin. Back in Hollywood, “A Single Man” director Tom Ford was stuck in London and had to miss the GLAAD awards to accept his trophy for “A Single Man” Saturday (Apr. 17). Ford’s partner, Richard Buckley, accepted the award on Ford’s behalf. Although “Twilight” star Kristen Stewart made it to the Coachella Valley Music and Arts festival this weekend, several popular bands — The Cribs, Los Campesinos!, Gary Numan and Bad Lieutenant — didn’t due to canceled flights.
British musicians  Delphic, Talvin Singh and Scottish rockers Frightened Rabbit and Chicago brass group Hypnotic Brass Ensemble, on tour in Europe, weren’t able to make it either. And it’s not over yet. The volcano is still spitting ash into the sky. Experts at  the University College London’s Aon Benfield Hazard Research Center told Reuters on Thursday, “If the eruption continues — and continues to produce ash — we could see repeated disruption over six months or so.” Travel chaos could extend into the new week, increasing the threat to New York’s Tribeca Film Festival, which begins Wednesday (Apr. 21). Filmmakers scheduled to fly in Monday (Apr. 19) to help promote their films — had already been grounded. Tribeca features films from nearly 40 countries, and many filmmakers from Europe were expected. Studio officials say the international junkets for “Iron Man 2,” starring Robert Downey Jr., and “Robin Hood,” starring  Russell Crowe — are still on for this weekend (Apr. 23-25)  in London. Cannes — May 12-23– is still up in the air. There are countless nonrefundable air tickets, hotels, yachts and mansions booked, and huge international film premieres and parties that may be sparsely attended or canceled altogether if the ash continues. Kristin Scott Thomas is skedded to emcee the opening festivities and director Mike Newell has a film in competition. Sean Penn and Naomi Watt’s film “Fair Game” will premiere. “Wall Street 2: Money Never Sleeps” starring LaBeouf, Mulligan, Brolin and Michael Douglas will premiere at the fest. So will Woody Allen’s film, “You Will Meet a Tall, Dark Stranger,” starring Watts, Brolin. What will happen to the festival voting if all the members of the jury can’t get there? No one knows. Tim Burton is the Cannes jury head this year and director Shekhar Kapur is also on the jury.
