Very good commentary - a lot of insight into technicalities and choices of camera movement made by Zemeckis. Some talk about the themes, but not too much, mostly at the end.

this was one of the first commenteries that i ever listened to back when this DVD was first released. And it still remains one of the best that ive heard.
Visual effects supervisors Ken Ralston and Steven Rosenbaum point out special effects that i didnt even realise were special effects. the highlights are when they point out what seem like single shots that are in fact two or three edited together and were shot in entirely different locations. Im hardly an expert on special and visual effects but this chat track is one of the most entertaining and educational ones ive listened to and one of the very few ive listened to more than once.

These three commentaries really should have been combined into one; the edited commentaries on "Forrest Gump" and "Cast Away" kept things consistently interesting, but here the participants struggle a little bit. Foster is the most engaging speaker, coming across as a cool and down-to-earth person as she talks about her approach to her character and production stories. Zemeckis, usually dependable for a good commentary, seems rather bored and lets Starkey do most of the talking; he perks up only at the end to discuss the film's thematics. Ralston and Rosenbaum go into a lot of detail about the film's technical challenges, but they aren't terribly exciting speakers.

I recently enjoyed Jodie Foster's commentary track for Contact. One of the first tracks I've listened to from my dvd's, it was a great mix of memories from shooting, insight into the character, and her appreciation of other people's work in the film.
