In contrast to the other three Lethal Weapon films, there does not appear to be a Director's Cut of Lethal Weapon 4 available in Region 1.
The Region 4 version of this disc misses out on; If you must have this film in spite of the sad excuse for a plot, or if you actually enjoy this crap, then Region 1 is the better version. Widescreen Review also state that the picture quality of the Region 1 version is blessed with "exceptionally rendered" colour fidelity, contrast, and shadow detail. In the end, it will come down to how much you are honestly willing to pay for this film - if you have approximately fifty-five dollars to spare, then Region 1 is the better choice. Otherwise, the two versions are almost identical.
