Highlander II: The Quickening (1991)

Continuity mistake: Near the end of the movie, Katana and Blake are worrying about the possibility that MacLeod has spoken with Neyman and knows the exact coordinates of the hole in the shield. That's odd, because a few scenes before we see Katana and Blake monitoring MacLeod as he speaks with Neyman in the prison Max. There Neyman tells the coordinates. So they know he knows.

Katana: The remains of your mortal wife. So frail. So earthy. So very dead.
Conner MacLeod: At least she's at peace.
Katana: Peace is highly overrated.
Conner MacLeod: Things don't change, Katana, I like that. After all these years, you're still a jerk.

Trivia: The producers didn't want to make a sequel to the original, but were pressed to do so by foreign investors due to the original being a hot-seller on VHS. During production, filming became a nightmare, as the script was constantly being re-written to contrive different ways to continue the story, and the film went over budget, causing the insurance companies involved to take over production and further "mess with" the storyline and effects to get it done quickly and cheaply. Director Russell Mulcahy was so ashamed of the finished film, he walked out of the premier before the end of the first act, and co-stars Christopher Lambert, Sean Connery and Michael Ironside have all admitted that the film was absolutely terrible. Lambert only finished filming because he was contractually obligated to the sequel, whereas Connery only made the film due to his friendship with Lambert and the steep paycheck he received, which he wanted to donate to charities he supported.

Question: Can anyone give a reason as to why he was made younger after being hit with that gas tanker with the lips? It's true that he was once again immortal, but that doesn't mean that he should've reverted to the age he was in the first film.
