If one's wedding is to include fireworks, a convoy of 50 luxury cars, a plane towing a message of congratulations and four helicopters, one cannot skimp on the pre-wedding video.

The groom, Salim Mehajer, understood this. So the young deputy mayor of Auburn - whose "out of control" nuptials shut down parts of the suburb of Lidcombe on Saturday - turned to professionals.

A month before the big day, Mr Mehajer employed a cinematographer, an assistant, a sound engineer and a narrator. The team spent at least 15 hours filming at locations such as Sydney University and the Opera House. The editor laboured for a week.
