An Inception 3D Blu-ray has not been formally announced at this time, and cinematographer Wally Pfister isn't sure if it will ever be released. He says that Warner Bros. is working on the conversion, but neither he nor Christopher Nolan are involved with it.
"I'm personally not a big 3-D fan. It doesn't really work for me. I don't like the glasses, I don't like the dark image, you know, through there. And it feels a little gimmicky to me. That's my own personal preference, I'm not a big fan of that. In terms of the immersion for the audience, we like to do things like film things in IMAX and put it on a much larger canvas and higher resolution rather than three-dimensional. So in terms of what's happening with Inception, you know, Chris and I are like-minded in that way. I don't know whether they're going release a DVD version in 3-D or not, but that's definitely [going to release]. It's just not something I'm that interested in as a filmmaker."
If Warner Bros. does decided to release Inception in 3D, it won't be until much later in the year.
Inception was released July 16th, 2010 and stars Leonardo DiCaprio, Ken Watanabe, Joseph Gordon-Levitt, Marion Cotillard, Ellen Page, Tom Hardy, Cillian Murphy, Tom Berenger. The film is directed by Christopher Nolan.
