Factual error: Supergirl spots Selina on school grounds and is about to leave the classroom to investigate, but Nigel, the teacher, stops her. In the background, you can see a small room with beige computers. These are BBC Model B computers, a UK computer that was typically used in UK schools and wasn't sold or available in the US, showing that the school featured in the movie is actually in the UK and not the US as depicted.
