Is there a way to open it in blender 2.7? I can't install blender 2.3.

It should all work in 2.7*

How did you find this question so quickly?

And it just gives black screen. Are you attempting to use the green screen file?

Already downloading it.

I was able to download and then load "Godiva Close" files (hcw_godiva_close.*.png). The only problem I encountered was the Hollywood Camera Work site's clip previews were not available (black). It worked for me using Blender 2.76b. For further assistance I will need a more detailed explanation of the difficulty you are experiencing.

Worked ok for me. I had to load the image files from disk as they were not packed in the blend file. ;) Here is a link to a render using 2.76b Blender Internal. https://cgcookie.com/image/quick-render-using-mr-skorupas-compositor-node-setup-wip/#discussion
