Reader YKYMF did us all a kindness by contacting Lionsgate directly to get some answers about the upcoming trilogy set. He was able to obtain some running time info that makes a well-built boxset even better.
• 90-minute “Still Screaming” documentary with 4 hours of extra footage
• 96-minute “Scream: The Inside Story” documentary
I’ll take a guess the 4 hours of extra footage includes an Audio Commentary that we know director Ryan Turek had participated in. Outside of that, I’d expect some extended interviews and special segments. There’s at least 7 hours of new content, not including all the previous extras from Scream to Scream 3.
Also, they list the number of discs as being… 4. So, that’s another question answered.
To the inevitable commenters still asking why Scream 4 isn’t included: different company. It’s just a cardboard box, and it would only be valid until Scream 5. The Scream trilogy is just that, a trilogy. Let Scream 4 stand next to it, metaphorically and literally.
