Marty Foster says she bought "Sherlock Holmes" on DVD at Wal-Mart. She got as far as the menu, before realizing someone switched the real DVD and replaced it with an adult movie.
Foster said, "it's not every day that you get porno in place of video that you think is going to be more family."
Foster says the clear wrapping and scotch tape on the outside should've been a dead giveaway. But didn't realize it until she got home.
The DVD also had a removable "Sherlock Holmes" label covering up the real disc.
Wal-Mart replaced the DVD for the real thing for free. The company is now investigating what happened.
