Taking to Instagram, Curtis explained that Princess Diana – along with her sons, Princes William and Harry – paid a visit to the cast of 1988 film A Fish Called Wanda.

“She was to visit our set deep in the gardens of Pinewood Studios with her children and we waited for her all morning,” recalls Curtis. “Then, when we took a break midday, I raced via golf cart to my dressing room to use the restroom.

“While I was in there someone came knocking on my door saying that Princess Diana and her children had arrived on set and as I raced back in the golf cart, they were already walking away.”

The actor continued: “The next day I wrote her a note explaining my nature break and how disappointed I was not to tell her, in person, how much I admired her.

“A hand-delivered letter from Kensington Palace, on her stationery, came the next day thanking me for mine and understanding completely the need for nature to take its course. We exchanged a hope that we would get to meet in the future.”
