IKEA Heights

Family, betrayal, sex, murder, and lots of melodrama: IKEA Heights is a soap opera shot at the IKEA store in Burbank, California in 2009-10. No, they didn't have permission from IKEA to do it, and some of the filming was quite an adventure. At first, store employees just assumed they had permission, but later the actors found their pictures were posted in the security room.

There's a bit of backstory about the series at reddit, when one of the actresses showed up to explain. There are seven episodes of IKEA Heights, and you can find them here. There's more information at the series blog. (via Daily of the Day)
