The Canadian movie theatre company says its Sensory Friendly Screenings will now include 17 additional theatres, for a total of 29.
The screenings include 2D projection, increased auditorium lighting, lower speaker volumes and smaller crowds.
Theatres also allow families to bring in outside food and take a break from screenings in a nearby "calm zone."
The screenings launched last month and take place on select Saturdays at 10:30 a.m., before theatres open to the general public.
The next one is on April 4 and will feature "Cinderella."
The program was developed in concert with Autism Speaks Canada.
