A famous movie star

William's Flat, also known as The Blue Door was featured in the 1999 romantic comedy "Notting Hill," starring Hugh Grant and Julia Roberts. It is still a popular destination for film tours and self-guided walks in Notting Hill.

The original blue door of William's Flat has been sold in an auction. It was replaced with a white door, which was later painted black, then white again. Today, William's Flat door is blue again.
