extended version of prometheus on dvd?

There is no extended version on any format; the alternate beginning and ending are in the form of deleted scenes. They are extras on the DVD.

I just bought my blue-ray/dvd disc today. Am watching the dvd at this very moment.

No there are no special features what so ever on the DVD, not even any deleted scenes I don't think. You had to buy the blu-ray for those at least for the alternate ending and beginning. As well as the majority if not all of the additional footage (making of documentary, interviews etc.).

@ It'sLikeAnAnthive: I have misunderstood something here. Are you saying that the Blu-Ray/DVD/Digital Copy that I just purchased yesterday does not have the 7 hours featurette?!!? Is that on the Collectors Edition????

as far as i know, you have to have the 4 disk version which includes the 3-d disk to have the seven hours of additional features. in that version the blu-ray disk contains the "deleted scenes". - i dont know if those scenes are also on the other blu-ray version that does not include the 7 hours of additional features. i have the 4 disk "collectors" version and there is no longer cut of the film. to my knowlege, a longer cut of the film is not commercially available in any format. only the theatrical cut and deleted scenes are accessed as a seperate feature. i hope this helps.

The DVD and the blu-ray do have the deleted scenes but that's it. The 3 disc blu-ray has the extended special features. There is no 4 disk version as far as I'm aware. There things aren't exactly hard to find out :P

Thanks, everyone.
