XXX star Vin Diesel has been forced to scrap a promotional trip to Australia due to film commitments. The action man was booked to appear on a number of radio and TV chat shows Down Under and he was recently announced as the guest of honour at an exclusive club party at Sydney's Rooty Hill club, scheduled for next week (05Oct07). But now Diesel has been forced to pull the plug on the whole trip. His publicist says, "Due to reasons beyond our control, the scheduled Vin Diesel appearances for Australia will be postponed until further notification. "Vin Diesel is currently in post production of Babylon AD, which has gone over schedule, and (we) are waiting on new dates and availability."
