Stephen King supposedly shot some extra gory death scenes for this movie. For example, the coach's death was more prolonged. But in the relatively conservative 80's, those deaths had to be trimmed. Wouldn't it be great to get a special edition blu-ray release which restores the cut gore. I'd love a King commentary reflecting on his experience directing. A cast commentary would be a lot of fun too. Sure it's cheesy and silly and not particularly good, but it is entertaining and never boring.
I'd be REALLY curious to hear what he says about it now, wonder if he'd be up for it. Also seconded on seeing a director's cut, although who knows if that footage exists any longer. (I was so sad when I found out those rumors of a gorier version being released in Europe were false.)
There's definitely a couple of shots in the movie that seem trimmed by a second or two to avoid gore, notably Pat Hingle's death (IIRC, we don't actually see him get hit?), and the preacher's death is very odd in that we see the kid react to his "body" but no shot of his face after he springs to life, and he dies completely off-camera making his whole prolonged survival seem rather pointless.
These felt like these were trims to me, even if only minimal, and it would be great to have an "uncut" version just for those to be restored. Ideally, I wish there were more scenes fleshing out the more minor characters (Leon Rippy's character, for example, or Giancarlo's!), but I don't know if anything more was shot on that front.
It was more than just trims, there were major gore sequences left on the cutting room floor. In some cases (e.g. the steamroller crushing the kid) there were two entirely different takes filmed- one with blood/gore, and one without.
I think there are a couple of examples in the behind the scenes stuff on the blu ray from 2018, but mostly they just talk about it without showing the footage.
