When Maxandra emotionally tells Mike that the performance has to be canceled they're standing outside the theatre in the pouring rain. Mike is wearing a thin white shirt which is quickly drenched. However when he returns to inside of the theatre in the next scene to tell the rest of the cast the shirt is completely dry.
When Maxandra and Mike meet dancer Sebastián Melo Taveira at the train station they are on platform 1-4 at St Pancras Station in London which is served by EMR (East Midlands Railway). In the film, Sebastián was travelling from mainland Europe which would mean taking the Eurostar which operates from platforms 5-10.
