Spacing it out will help to fill in some of the negative space above and below the text block.
I think your back layout could benefit from some ways of "breaking up" each element. What about something like this?

Here's what I did...
- Adjusted line spacing on synopsis.
- Moved Special Features down a bit.
- Added a white divider line between synopsis and features. I made the divider in Illustrator with a horizontal line and the default Charcoal Feather brush, then copied it over into Photoshop.
- Added some dark red blood smear/drip/stain along the top. I painted it in with a brush, but you can take your time making it look cleaner than I did. Notice how the bottom edge of the blood roughly aligns with the bottom edge of the barcode.
In my opinion, these little additions help to separate each section and also resolves some issues with negative space.
I didn't include it my example, but another thing you could do is bold the title of each Special Feature (Return to the Overlook, The Making of Dr. Sleep: A New Vision, and From Shining to Sleep). Varying the font weight in this subtle way will help to visually separate the title from the rest of the info (HD, time, description). It also helps add a little bit of style to what would otherwise just be a "boring" line of text. It also makes it look like you spent a bit more time on it instead of just typing in text and moving on... not saying that's what you did in this case, but going that little extra mile will help out a lot.
EDIT:
While I'm preaching about "using negative space," what about adding the Overlook Hotel beneath Ewan's face? If you can't find a run-down, boarded-up version like in Doctor Sleep, you can always find a lot of photos of it by searching Stanley Hotel in Colorado, where the original Shining was shot. Here's a quick example using a generic photo of the Stanley...
