Continuity mistake: In a scene where Marisa Tomei visits Christian Slater at his home, she unties her scarf. A minute later, it is shown tied. Then she unties it for a second time.
Factual error: After Marisa is almost raped by those 2 guys, she wants to be driven to work. Her brother drops her off, but wouldn't give her the car because he had school the next day. But it was the day before Christmas Eve that night, and who has school on Christmas Eve?
Factual error: The game was supposed to be taking place at the Minnesota North Stars' arena. But the Red Wings were wearing home uniforms, which they only wore at the Joe Louis Arena.
Suggested correction: The uniforms are correct. In the NHL, the home team traditionally wears dark uniforms and the visiting team traditionally wears white uniforms. Here, the Red Wings are wearing white uniforms, indicating that they are the visiting team.
From 1970-2003, NHL home teams wore their white jerseys, so the uniforms would be wrong. It wasn't until the 2003-2004 season did home teams start wearing their dark uniforms. The scene was shot at the Met Center, but it doesn't seem to be a real home game since during the 1992-1993 season, the North Stars were never ahead of the Red Wings 4-2 at home (but they did win 4-2 in Dec '92 in Detroit). North Stars did have a 4-2 lead at home in game 3 of the 1992 Playoffs, but were in white.
The film's Met Center scene was shot during an actual game in Minnesota in April 1992, which was the 1991-92 season. The North Stars did indeed wear their "road" black jerseys for select home games that 25th Anniversary season. I know this as I was employed by the team at that time.
Continuity mistake: When the two guys are beating on the cigarette machine, Caroline gets him the pack he wants (after he tells her two different brands), and she has the two packs he didn't want in her hands. When she walks away, the packs are no longer in her hands.
Continuity mistake: In the beginning of the movie, Marissa is looking in the mirror and getting ready when her "date" pulls up, so she throws all her makeup into her purse. In the next shot it shows her running in front of the mirror to leave her room and the make up is back on her armoire.
