The largest provider of on video-on-demand to U.S. hotels, LodgeNet, has released their numbers for the past year and the #1 movie watched in hotel rooms was The Da Vinci Code.
We're not sure what the correlation between bad movies and hotel rooms is, but here's the rest of the top 5:
2. The Break-Up
3. Failure to Launch
4. Walk the Line
5. The Devil Wears Prada
LodgeNet prefers not to rate or publish the number of requests for their "adult" fare but we can safely assume that their sales dwarfed those of Failure to Launch. In relation to Blockbuster's numbers for the year, Walk the Line was the only movie to figure in both Top 5's.
