The filming of the new Dr Who series has seen Charlestown's popular harbour taken over by a film crew.
BBC Cornwall's Chris Young has visited the film set near St Austell. Click on the audio link to hear his report.
There may be a tall ship in the port, but it's surrounded by several flood lights.
The crew were filming from 4pm on Tuesday 1 February into the early hours of Wednesday morning.
Rachel who works at the local pub in Charlestown watched it all happening.
She said: "It was a really good experience with all the special effects. If you do want to go down it's well worth it, but be very quiet."
"We had Alice in Wonderland filming last year, but it wasn't as big as this."
It's not the first time Dr Who has been filmed in Cornwall. Back in 1975, filming took place around the clay pits of St Austell.
Charlestown has been used in huge productions in recent years including the latest version of Alice in Wonderland, The Eagle has Landed, Frenchman's Creek, The Onedin Line, The Three Musketeers and Rebecca.
Locals believe a remake of the classic Jason and the Argonauts will be filmed in Charlestown later this year.
