As previously reported here on Newswire, 20th Century Fox has begun selling rental DVDs completely devoid of the special features available on their retail product. Well, there's been a hitch in that plan: This week's release of Slumdog Millionaire has gotten all cocked-up, and scores of copies of the rental version of Slumdog have made their way into the hands of people who bought what they thought was going to be the full-featured version. Fox has set up a hot-line (1-888-223-4FOX) to handle requests for replacement copies, but at the moment, it sure doesn't seem like this cost-cutting measure is saving the studio much money.
