So this was maybe 8-10 years ago. Me and my uncle were watching a movie. All I can remember is that there were a few people and one of them releases these creatures. They kinda looked like pac men but not exactly.. I dont know how to quite explain them. After they’re released, the people escape on a plane to somewhere else as the world dissappears. Maybe?? This is the only scene I can remember. No specific actors but if I am correct it played on tv. So it was kind of a known movie im guessing!
That sounds a lot like “The Langoliers,” a Stephen King story that was adapted as a TV miniseries. Here is a link to the Wikipedia page detailing the plot.
