In case you're wondering, that is 1,179 minutes, or just under 20 hours, of Hogwarts letters, Quidditch matches, Polyjuice potion and Patronus charms. And you'll want to budget in some extra time for all of the magical bonus features on the last Blu-ray in the series including nine behind-the-scenes featurettes and a very special interview between Daniel Radcliffe and J.K. Rowling.
Here are our seven tips for a successful Thanksgiving Potter marathon:
1. Start early. It seems weird to start watching a movie first thing in the morning, but you have no chance of finishing without falling asleep unless you skip the Thanksgiving Parade and pop in 'Sorcerer's Stone.'
2. Even if the most delicious smells begin to apparate from the kitchen, resist the urge to hit the pause button. You need to get at least part-way through 'Goblet of Fire' before taking a break for Thanksgiving dinner. Tell Grandma she better time that turkey to be ready no earlier than 3PM.
3. Practice shouting, 'NO MOM, I CAN'T HELP SET THE TABLE. I'M BUSY MAKING HISTORY!'
4. At dinner, refrain from making references to dining in Hogwart's Great Hall. No 'I wish this apple cider was butter beer' remarks allowed. Your family already knows you're a nerd. No need to make things worse.
5. Go light on the turkey as it contains Tryptophan, which can make you sleepy. There's no way you're making it through all eight movies unless you pass on seconds of turkey. We suggest carb loading with yams instead.
6. Make sure you finish eating first so you can go claim the TV for the rest of the evening. Otherwise, the football fans in your family will squash your marathon faster than you can say 'Expelliarmus.'
7. Scarf down some pumpkin pie during our favorite scene in 'Deathly Hallows Part One' when Harry and Hermione dance to Nick Cave's song in the tent. We're getting misty just thinking about it. Harry and Hermione all grown up.
