Star Trek IV - The Voyage Home
- USA theatrical version - released on Blu-ray
- UK theatrical version called “The Voyage Home : Star Trek” - apparently released on VHS?
- PAL DVD version - DVD - features a new beginning containing a montage of scenes from Star Trek II and III
- are there any more versions?
The “story so far” montage seen on the PAL DVD release was not new. It was present in the UK theatrical version in 1986 (I saw it) and it was also present on the version of ST IV included in the UK VHS TOS era widescreen collection.
Star Trek VI - The Undiscovered Country
- theatrical version - released on Blu-ray
- VHS/Laserdisc version - released on LD/VHS
- DVD version - released on DVD
Are there any more versions? 3 different cuts doesn’t seem like enough, since Nick Meyer is a bit of a George Lucas and he tries to re-do his films constantly. I also heard that the REAL theatrical version had different closing credits, but I never managed to find any evidence of its existence.
There are two DVD releases of ST VI. The original, which is the same cut as the VHS/LD release and then a special edition, with a different aspect ratio (1.78:1) and the faces of the conspirators are shown during Valeris’ mind meld interrogation.
