Death in Paradise star Ralf Little has said it was a "Herculean effort" to get the show finished in time for its usual winter broadcast.
The BBC One detective show is filmed on the French Caribbean island of Guadeloupe.
Speaking on BBC Breakfast, he said: "We only finished a couple of weeks ago, which seems insane now to say it because it seems like a lifetime ago.
"I think I left the island on the 20th of December just in time for Christmas. It has been very hard work, if I may say, quite an achievement, to have got it all done in time."
Little said the production started more than two months behind schedule.
He added: "We made a commitment and the company made a commitment to try and get the show broadcast at the same time this year as any normal year.
"So it has been a real Herculean effort to get it done on a real-time crunch. And yet here we are and we seem to have managed it."
Yes, it's Monday. But on the bright side... #DeathInParadise series 10 starts this week! So that's something to look forward to. pic.twitter.com/PxYAO4XeSq
