DOCTOR Who bosses fear major spoilers leaking before the new series even begins after a script went astray.
BBC sleuths were able to track the dossier down to a computer server in Brazil - where Time Lord actor Ncuti Gatwa had just been on holiday.
Showrunner Russell T Davies said it would be a miracle if they are able to reach the current series finale without details being leaked.
In a joint interview alongside Ncuti, he told SFX magazine: “I just hope we can get from here to transmission without things being spoiled, because things do get spoiled.
“And things get spoiled to an extraordinary degree.
“We found one script – I’m going to say this – we found one script on an open server in Brazil.

“It’s nuts. That’s what happens.”
Sex Education star Ncuti then chipped in: “I was going to say, oh my god — I was in Brazil.”
But Russell quickly added: “It wasn’t you.”
Ncuti, 31, was first seen as the 15th Doctor at Christmas.
