This film was released without the alien subtitles on the disc, this has now been rectified and all future stock will be produced with the subs included, in retailers from Monday 27th March. The way to be sure that they are on the copy you buy is that they will be listed an an extra on the front along with "poster & reversible sleeve".
Sainsbury's exclusive Blu-Ray will show "English subtitles" option on the back cover, if it doesn't list subtitles then it will be the version without alien subs.
If you have purchased a copy of the film already or happen to buy one in the future without the subtitles included and you want a correct, replacement copy then please do the following:
Take a photo of the physical product alongside the receipt/email proof of purchase and email to us at the 101 Films info email address: info(at)101-films(dot)com. Write "Alien Nation replacement" in the subject field and include your postal address.
We will then be happy to send you a replacement copy free of charge.
This appears to apply only to the new UK release, not the Umbrella release.
