Even on the first Batman special edition, Sam Hamm discusses aspects of the script that he does not want to be held responsible for.

The Mallrats one is an excellent view of why it bombed, as already mentioned by a previous poster.

PCU: There's a commentary on there from Jeremy Piven. I seem to recall him being pretty pissed about a few things. The one thing that sticks is that no one was allowed to improvise at all.

Gremlins 2: only heard a moment or two of the commentary to get sample, and I believe the director starts by saying "Welcome to the most unnecessary sequel ever."

Rules of Attraction: This thing has at least 3 commentaries...and one of them is from someone who had NOTHING to do with the film at all: Carrot Top! It seems like it's the first time he's ever seen the film as he calls commentary and seems to either want to fuck women that are on screen or hit up Eric Stoltz for an acting job. I've gotta think that there's some other goofy shit amongst the other commentaries and perhaps some criticism of the film in some capacity. Haven't heard any of the other commentaries yet.

I don't think it was a bomb, but listen to the commentary on The Sum of All Fears. Hilarious stuff. Tom Clancy is paired up with the director, Phil Alden Robinson. Clancy introduces himself as something like "the author of the book they pretty much ignored." At various points in the film, Clancy says things like "they wouldn't do it like this" or "now this scene is complete bullshit." What makes it so good is that Robinson is right there, and has to wheedle his way through those comments. Clancy is clearly the dominant personality, and Robinson comes off as a weenie.

(Shocking revelation: Clancy agrees that Affleck is a good choice for Ryan-- inexplicable as it is clear to anyone with eyes that Affleck can't credibly play a character with above average intelligence.)

Mickey Rourke's commentary and interviews on Angel Heart were classic to me. He hated the movie, and said he gave zero effort in his starring role.

He didn't seem too impressed working with Robert De Niro, which I found really strange (but only cause De Niro is my favorite actor).

I thought it was funny how he called out a few random people, including some past directors he worked with. He also called Bill Cosby a chicken shit.

From "The Simpsons" "Monty can't buy me love" (May 2, 99)

Lisa watches "The Postman" on a big screen TV.

Lisa: Ooh, I hear this really sucks.
[she presses a button for director's commentary and Kevin Costner
appears in a split screen]
Costner: I'm sorry. I am really sorry. Ugh, ah, I don't know what I was
thinking, but "Field of Dreams" was good, wasn't it? Made us all
believe again.
Lisa: Oh, poor Mr. Costner. He tries so hard.
Costner: Aw, thanks, you're sweet to say that.
Lisa: Uh ... where are you?
Costner: [steps out from behind the TV] I'm back here. Hi, will you bring me
a sandwich? Please? No, no crusts.

Lol. It's funny he says that, but on one of the commentaries for the original at the end, he says "I actually prefer the sequel".

I think the only reason Clancy liked Affleck in the role is that he was younger than Harrison Ford. As I recall, Clancy was very upset about Harrison Ford being cast in the previous two Jack Ryan movies.

Clancy is a huge pain in the ass and went public with his dislike for Harrison Ford right from the beginning. Too bad because I absolutely loved Patriot Games and CAPD. That said, I refuse to watch the SOAF.

The commentary in Titan A.E. discusses this a bit.

The Little Nicky commentary addresses things somewhat, talking about how the studio kept trying to talk Sandler out of using that voice because people would hate it.

Wow, for once studio schmoes were RIGHT.
