I did a search for both Black and Dhalia and couldn't find anything.

Has anyone heard when this will be out on HD-DVD?

You are spelling Dahlia incorrectly. Here are the threads on the topic:

There were others too.

I watched this last night on DVD and can honestly say this was the worst movie I had seen in a while.

Odd, I did a search for black too and nothing showed up. So basically it's not coming soon, bummer. I guess I'll watch the DVD then.

Try Hollywoodland, in some ways a similar film, much better, and available on HD DVD (I haven't seen the disk but HDD gave it a good review).

Eh, I was excited about the Black Dahlia, and rented the DVD, and I am glad I did. The movie sucked. It was boring and nothing like I thought it was supposed to be.
