Hmmm. Aside from the "sit-down" interview (but why only those two actors?) the extras sounds rather lame. But I know this is not a complete list of the extras by any means.
What I want: a commentary track, deleted scenes, bloopers, a featurette on the "neutron cream" prank, and a proper making-of documentary... I'd also love a second commentary track with the cast, but I won't hold my breath for that one.
But thank you for passing along the news. I'll definitely be buying this.
