With nearly 400 movies on the roster, one would have to sit for three weeks straight to see them all.
But for many of the 80 per cent of Canadians who suffer from back pain, the thought of sitting through just one feature film is enough to make them cringe.
Suffer not the screenings
Whether you're a die-hard cinephile determined to achieve maximum movie time, or you're just catching a flick after work, there are some easy things you can do to avoid an aching back.
Dr. Sid Lisser is a chiropractor, acupuncturist and action movie buff living in Toronto.
Despite his own experience with back pain, Lisser satiates his appetite for movies by watching at least a couple every week.
"Sitting in any position for a long period is bad for you," he warns. "If I know I’m going to see a long movie then I’ll actually bring a sweater. I roll it up and put it behind my back, or I'll sit on it so I can raise my butt."
He also follows the following ergonomic rules for successful screenings:
"Your knees should be equal to or slightly lower than your hips, the backs of your knees should always be two inches away from the seat pan. You should be as upright as possible," he said.
"I don't use the recline feature on the seats … and generally speaking, if you're there for long periods of time, use a lumbar support."
It's not just how you're sitting that's the issue, but also for how long. Lisser says movement is key.
"If I were [watching days of screenings], I would be in the back row, I would stand as much as possible ... I'd sit beside the aisle and stand up. My seat is always in the back row right beside the aisle."
Before the lights go down
There are also preventative measures moviegoers can take long before the lights go down.
"Before you go to the movie theatre, go see your health-care provider," Lisser suggests.
"You can get a massage therapist to massage you and kind of preemptively loosen your muscles, or chiropractic or physical therapy. They're all equally amazing."
Additionally, keeping spinal discs hydrated by drinking lots of water and loosening muscles by stretching can also help.
TIFF's longest film, the black-and-white Filipino drama From What is Before, clocks in at over 5½ hours. Not only will drinking water before a movie that long help keep your discs lubricated, it'll also guarantee a trip or two to the restroom, which would offer a back-friendly opportunity for stretching your legs.
