The scene in the train station where a young boy smiles at Cyclops and he smiles back was unplanned. The boy was a huge X-Men fan, and Cyclops was his favorite. The scene originally called for Cyclops to look at the train schedule, but according to Bryan Singer the boy could not stop smiling at James Marsden. Finally, during one shot, Marsden just looked back at him and smiled, much to the boy’s delight. Bryan Singer liked the idea so much, he kept it in the film
