What are some good movie themes for a high school blood drive?

I'm in AP Biology at my high school and every year we host a blood drive. There's always a theme. Last years was "Finding Hemo; Just keep giving" Like off of "FInding Nemo; Just keep swimming". We've also had "Prick Me I'm Irish" And "Blood, is it in you?" I would really like to use a Disney movie theme, so it would be appropriate and cute. I need all the ideas I can get! Thanks so much!
