The TV miniseries was a huge hit when it aired earlier this year (16), propelling Tom, who played hotel worker turned spy Jonathan Pine, to worldwide fame.
There has been much speculation about a second season of the programme, and Olivia, who starred as enforcement agency boss Angela Burr in the show, has said that if they were asked, the whole cast would jump at the chance.
"You'd have to be a complete idiot to say no," Olivia told Deadline Hollywood. "I think that if they called we'd all say yes. But I don't know. I haven't heard yet if they're doing this or not."
The Night Manager was based on the book of the same name by John Le Carre. Speaking about the prospect of a follow-up season earlier this year (16), Tom, who has also achieved notoriety through his relationship with pop star Taylor Swift, explained it would be up to Le Carre to create a further storyline for his characters.
"Truthfully, I think it is still in the lap of Le Carre himself," Tom told Entertainment Weekly. "I think we're all aware that there is an appetite for more, but it really lies with the author, as it should, and if he can see a way for them to continue in a framework that fits his original conception."
Another person also up for a second series is David Harewood, who played US agent Joel Steadman in the show. Joel was heavily involved in bringing Hugh Laurie's villain to justice and also had a back story with Olivia that was never fully detailed.
Speaking to Digital Spy, David said: "I would crawl across broken glass to work with Olivia again. She's fantastic - a really wonderful actress. I thought we made quite a nice team - so I'd like to explore their relationship and see them working together again, for sure."
