Frequently Asked Questions
How do I find exact movie runtimes?
Check IMDb, Wikipedia, or your streaming service for accurate runtimes. Remember that theatrical versions may differ from extended/director's cuts by 10-30 minutes or more.
What about credits and post-credits scenes?
Movie runtimes typically include credits. If you skip credits, subtract 5-10 minutes per movie. For Marvel films, you might want to keep credits time for those post-credits scenes!
How long is too long for a marathon?
Studies suggest attention and enjoyment decrease significantly after 4-5 hours of continuous viewing. Consider spreading longer marathons across multiple days or taking substantial meal breaks.
Should I include snack/meal breaks?
The break duration setting can include quick bathroom/snack breaks. For meal breaks during longer marathons, add extra time or set a longer break duration between specific movies.
