T.V. versions has two extra scenes. One featuring a walk with Nick Nolte and Annette O'Toole and a scene that occurs after the shootout at the B.A.R.T. Station between Cates and the Police Chief. The Chief tells him that Internal Affairs is on his back. Other scenes are extended by a few seconds and Denise Crosby is wearing a bra and panties in the T.V. version instead of being naked.
The original UK version of 48 HRS. was released with a '15' rating on CIC video in the mid-1980s, but had every swear word edited out of it (what was basically the TV version). The film was re-released on CIC video in the early 1990s in an 'uncut' version with all language left in, rated '18'. Strangely, both versions on CIC video altered Reggie's singing in the prison cell. Whereas in the original version of the film he was singing "Roxanne" by the Police, on the video he is singing a different song, probably because of copyright/licensing reasons - it has even been removed from the end credits. In order to remove the song it was dubbed in by an Eddie Murphy soundalike, but the other dialogue in the scene (when you can hear Reggie's singing in the background) had to be dubbed over as well. This has ended up with Jack's dialogue being spoken by someone other than Nick Nolte. The replacement actor's voice is very high-pitched, which is unintentionally rather amusing.
The Swedish version was cut by 3 1/2 min by the censors. The shootout at the hotel (and some violence to some women) was shortened by almost 2 min, the beating of Luther was omitted by 24 sec, the fist fight between Cates and Hammond was missing 57 sec of violence. The gundown of Ganz was also removed.
