I think this birthday party idea is really cool. I got most of the things from this website.Well to start off with  INVITATIONS:the invitations are movie tickets.(COMPUTER)put in the shape of a movie ticket.On the ''ticket'' print ''ADMIT ONE'' ''Come and join _______ in his/her movie theater party!!!'' INSIDE ''TICKET'': Where:,when:,time:,RSVP:.DECORATIONS:Most of the theater colors are:Red,Silver,White,and blue.So try to buy balloons,streamers,other decorations that color.TREATS:You could buy popcorn bags and put sweet tarts,pixie sticks,hershey chocolate bars,etc.FOOD:For the food you could make a square cake and write:''happy birthday _______!!!!!'',tostitos,chess dip,corn dogs,and hot dogs.THE PARTY:Give every guest a zip-loc baggie with fake tickets inside(dollar store/oriental trading co).try and find or build a ticket booth that someone can get into.The tickets are so they can bring a friend or relative and pay ther ''ticket'' by the ticket booth.Pick 2 movies that you think is appropriate for kids.Watch those movies and after them let the kids have as much fun as they want until they get tired and fall asleep.(tell the kids that if they fall asleep first they get to have whipped cream put on thier face when they get up-optional-)If most of the kids are still sleeping when their mom/dad get therehave some tea with them or talk.when the kids awake give each of them 1 of the popcorn bag with favors in them.THANK YOUS:Don't forget to take pictures so you can put them on the thank you cards.on the thank you cards write/print :here's a candy & thank you for joining _______ at his/her party''.I hope i gave you a few  ideas to make your party planning easier."
