"Warner’s home entertainment division has engaged Prime Focus to convert two back titles in the [Harry Porrter] series for 3D Blu-ray: ‘Harry Potter and the Order of the Phoenix’ and ‘Harry Potter and the Half-Blood Prince,’ " according to Variety. [Please note: Variety is behind a fire wall and may charge you to read this story.]

Interestingly, this news comes on the heels of Warner Bros.’ movie division putting the brakes on trying to have a theatrical version of the latest Harry Potter movie, "Deathly Hallows: Part 1" done in 3D in time for that movie’s theatrical release later this year.

 The article says, "Studio is keeping mum about its 3D plans for the "Potter" backtitles, including street dates for 3D homevideo and whether there will be a theatrical re-release for the series. With the final four "Potter" pics in 3D, however, conversion of the earlier pics seems likely."

The question we here at TVWeek wonder is how much library product the studios will convert to 3D Blu-Ray. The more product that is available, the liklihood the more 3D ready TV sets can be sold.

Already George Lucas has said that he’s converting his "Star Wars" movies into 3D. And DreamWorks Animation chief Jeffrey Katzenberg, who is a major supporter of 3D for theatrical release, has said that his company was going to convert some of its library titles to 3D as well.

The Variety article notes that when Warner Bros. released their animated hit "Happy Feet" several years ago it had been slated for a 3D release, but the company ran into the problem of not having enough lead time to do it before the film had to be in theaters. At some point Warner Bros. could convert it to 3D Blu-Ray.
