After much anticipation, I finally saw 500 Days of Summer and loved it! Aside from the easy, romantic soundtrack, hip wardrobes, and counterintuitively hopeful plot, I fell for the movie's interiors, which are charming, inspiring, and easy to reproduce. In the film, Summer (Zooey Deschanel) is a recent transplant, and still has a few boxes sitting unpacked in her apartment. She also has plenty of interesting, vintage artwork in ornate gold frames, some well-traveled knickknacks, and as you might expect from any good indie flick, some cool posters. The most noticeable element of her apartment (a studio, I think) is the blue toile wallpaper you see upon entrance. French toile patterns date back to the 17th century, and they saw a rejuvenation in popularity about 10 years ago, when an antique or country look in interiors became popular. It's unusual to see it used in a city apartment, let alone that of a young woman. But somehow it works flawlessly for Summer, who rides around in a bicycle with a wicker basket, and is seen in conservative ensembles like wide-legged trousers with a vest (a girlish Annie Hall) or delicate, 1940s-style sundresses.

You can find a similar blue toile paper by the Wallpaper Company at Home Depot. But, Thibaut Design is also known for making beautiful toiles.
A streamlined iron framed bed with a bit of a vintage feel to it is key. The Pottery Barn Savannah Bed & Headboard ($249-799) is a close match. Summer has strung Christmas tree lights on the frame of hers, giving it a romantic, ambient look when lit. Her nearly white bedding has a subtle pattern, giving it a well-washed, antique look. And, a patchwork throw pillow has nostalgic style. Here are a few products to help you get the look. Source
