We don't know the name of the project or the fees involved but a casting call has been sent out for strong swimmers in Dublin.
A shoot is scheduled for next week in Dublin and the only requirements are the ability to swim and being comfortable jumping in and out of the sea for a number of hours.
No acting experience is necessary and the organisers of the mystery shoot are eager for a diverse group of swimmers.
A casting call on MovieExtras.ie reads: "We're hoping to hear from all ages, genders, with a special emphasis on people from diverse backgrounds and different ethnicity.
"No performance experience necessary! You will be swimming in the sea and need to be happy to jump in and out of the water."
The shoot will last for one day and will take place at some stage next week - either 30 or 31 October or 1 November.
The rate is not specified on the website, although the casting call does assure candidates that it is a fully-paid role.
