Summit Entertainment, the studio that made the Twilight series, is doing its best to make sure that if you want to see a vampire brooding, you do it through Summit. The company seems to be lobbing lawsuits at pretty much anyone who uses Twilight's name or images without its permission.
Edward and Bella doing what they do best: gazing longingly at one another.
… Summit also objects to fans making Twilight T-shirts without its approval. In 2009, the company demanded that Zazzle.com, a service that lets people upload, print and sell their own clothing designs, remove its users' Twilight-themed T-shirts from its site.
The company also sued Topics Entertainment for making a documentary about Forks, WA., the real-life town where the Twilight books and films take place. Among other claims, Summit accused Topics of copyright infringement because both the DVD cover of that documentary and the DVD cover of Summit's own documentary on the town featured a moonlit forest.
