I know parents with kids, my grandparents, and some ladies I know as well would LOVE this site. RunPee.com lets you know exactly when it’s ok to run to the bathroom so you won’t miss anything significant in the film you’re watching.
They organize the films by release date, running time, alphabetical order, and a classics section. The site is fairly new and can be slow to load, but if you’ve got the patience and the need, go visit http://www.runpee.com
I recently saw Night at the Museum 2: Battle of the Smithsonian and here is a great example from RunPee.com’s site on how you know when you can run and pee during this film. If you click on the white dots, they will describe each point you should run and pee. The site is still in Beta form, but is great as is and can only get better.
Special thanks to JoBlo.com for posting this originally. I go there first when it comes to fun stuff relating to film.
