Eddie Redmayne told RTÉ Entertainment that his palms were sweaty reading the script for Fantastic Beasts: The Crimes of Grindelwald, with the twists and turns making him need to read it a second time straight away.
Redmayne reprises his role as Newt Scamander in the follow-up to 2016's Fantastic Beasts and Where to Find Them, and he couldn't get over some of the "jaw-dropping" moments in the film.
"I literally got sweaty palms as I read the script and then I finished the script, took one massive deep breath, downed a glass of water and started all over again," Redmayne told RTÉ Entertainment.
"I was like, 'Is this real'. It's pretty jaw-dropping, isn't it?"
The first film was set in New York, The Crimes of Grindelwald sees matters move to Paris, and it's looking like the next instalment will be set in Rio de Janeiro, with JK Rowling tweeting that to her fans.
"Jo tweeted that the next one might be set in Rio de Janeiro so we found that out with the rest of the world, so Newt and Tina on the Copacabana Beach maybe?" Redmayne said before adding that he is "genuinely stalking JR Rowling on Twitter" in a bid for information.
