Sydney, Jun 11 (IANS): Despite being busy promoting his latest film "World War Z", Hollywood actor Brad Pitt made sure to spend time with his son Pax during his recent promotional visit to Australia.

The 49-year-old took Pax on a boat trip while in Sydney and they spent some quality time on board a yacht named Ghost, a statement said.

Brad feels it is essential to find time for family.

"I always thought that if I wanted to do a family, I wanted to do it big. I hate it when they're gone. I hate it. Maybe it's nice to be in a hotel room for a day - 'Oh nice, I can finally read a paper' ... But then, by the next day, I miss that cacophony, all that life," he said.

The night before the boat trip, Brad walked the red carpet for the Australian premiere of his film on Sunday. Pax, however, wasn't in attendance.

Brad has been at the top of worldwide promotions and has even surprised his fans at the film's multiple screenings at Atlanta, Philadelphia, Chicago, Austin and Los Angeles.
