Van Damme and Lundgren are also part of the commentary. They are both recorded separately, they offer some small tidbits, but at the end of the day they are overshadowed by Devlin and Emmerich.

Speaking of Devlin and Emmerich, they're both in one room and clearly in a good mood. They have fun with certain scenes and focus on the difference between the early 90's action movies and the more recent ones. They poke fun at certain moments, they laugh a lot, but it's pretty clear they're both ultimately happy with the finished product.

They cover everything - from shooting locations, what was available to them at the time (in terms of technology), the story ("In essence it's a Pinocchio story", says Devlin), the cast, to the fact that they weren't allowed to mention CNN. And yes, they do talk about that great looking truck.

Commentary's definitely worth it. Especially if you're a fan of the movie.
