Neither phantom bed bugs, nor last-minute tweaks or gossipy tweets will stop the Toronto Film Festival throwing the doors open to its new headquarters on Sept. 12.

Public party plans for the TIFF Bell Lightbox opening were unveiled Tuesday, including a block party that will run from 11a.m. to 4 p.m. complete with a noon ribbon-cutting ceremony, a family fun zone and musical performances.

Inside the Lightbox, visitors can explore free screenings in each of the five state-of-the-art cinemas, the Essential Cinema exhibition and film-based artworks from major international artists throughout the building.

As followers of breaking Toronto festival buzz already know, rumors of a bed bug infestation at the Cineplex Scotiabank complex being used for press and industry screenings were quashed on Monday.

The organization’s main preoccupation now is removing the worker bees from its new headquarters, the Lightbox, where an orientation session with volunteers last weekend had to be moved at the last minute to Roy Thomson Hall.

While the hard hats are finally off at Lightbox, a fest spokesperson said Tuesday that audio-visual and other equipment in the facility is still being tested.

The resulting traffic jam means staff, volunteers, service suppliers and other stakeholders must await their turn to get into the building — sure to create moments of high drama behind the scenes in the 11th hour.

A fest spokesperson said trade workers will be on hand during the fest to address any issues at the Lightbox, which will host a range of industry events and film screenings.
