With a rather peculiar takedown request Hollywood is going after OpenCulture.com, one of the largest collections of cultural and educational media online. According to a takedown notices the MPAA sent to Google, Open Culture's list of 700 free public domain movies contains copyright infringing material.

Despite the growing availability of legal services in many countries, movie studios face a constant stream of pirated films.

In an attempt to deter these infringements, the MPAA and individual movie studios send thousands of takedown notices to Internet services every month. Most of these requests are directed at Google.

When it comes to takedown notices the MPAA has a dubious track record. The movie industry group has got into the habit of asking Google to remove the homepages of allegedly infringing sites instead of individual pages where the infringing movies are listed.

A few days ago, for example, the MPAA asked Google to remove the homepage of the most popular torrent site Kickass.so, alongside several other torrent and streaming sites. As with previous requests Google declined to do so as the request was too broad.

The same takedown notice includes another unusual and perhaps more worrying request. Between all the “pirate sites” the MPAA also targeted Open Culture’s list of public domain movies.

For those unfamiliar with the project, Open Culture offers an archive of high-quality cultural & educational media. With Stanford University’s Dan Colman as founder and lead editor, the content listed on the site is selected with great care.

The MPAA, however, appears to have spotted a problem with the list and has asked Google to remove the entire page (containing 700 movies) from its search results, as shown in the image below.

So why would MPAA target content that’s seemingly in the public domain?

The full details of the takedown notice have yet to be published, but there is a good chance that the request was sent in error.

In any case, the notice doesn’t look good for the MPAA. Over the past several months the MPAA has lobbied Google to block entire domains from its search results, but mistakes like these are a reminder for Google to remain cautious.
