I don’t remember much about this movie but I know I saw it on tv maybe 5 years ago. It was about an EMP and I remember a group of people stuck in an elevator, they try to get out of it, one guy falls, the rest make it to the roof where they are still stuck and unable to get help. After a few days one guy dies up there. I think it spans over only about a week or so before things start working again. I remember another scene where people are bbqing all their frozen food the first day of it. I remember there was someone able to use their phone for some things due to having a solar charger. It seemed realistic as far as those types of movies go.
