Alligator (1980) / Alligator II (1991)
UK Anchor Bay DVD (2-movie set)
1. both discs are region 0
2. Alligator (1980) is regular PAL, not an NTSC > PAL conversion. The runtime is correct (87:03 PAL) (Note this is the same runtime as the German 25fps Blu-ray).
This presumably means that all the other PAL releases with stated runtimes are also regular PAL.
However, the stated runtime of the US Lions Gate release (86:54 NTSC) is anomalous, so presumably either this is a PAL > NTSC conversion, or it is cut, but I don't own it.
