Some theaters are Yoo Jungadding health warnings to their ticket counters in the wake of a Twitter thread about strobe light effects in Incredibles 2.

Blogger and advocate Veronica Lewis tweeted the thread on Friday, writing that the film's liberal use of flashing light -- in one scene, for 90 seconds straight -- could cause issues for viewers with epilepsy, migraines, or chronic illness.

"I am not calling for a boycott of Incredibles 2, or to change the movie ... I just wish Disney/Pixar and theaters alike would issue a warning that the movie contains several scenes with strobe lights," she wrote.

"Parents have the right to make an informed decision about something that could impact their child’s safety and people with chronic illness have the right to learn about potential triggers/make steps to avoid them."

Now, Varietyreported Saturday, Disney has asked theaters to add signs alerting moviegoers who might be photosensitive.
