The actor, 42, and actress, 36, who star as Jackal and Bianca in the thriller series The Day of the Jackal, joined host Nick Grimshaw, 40, on BBC Radio 1 on Thursday.
However, Eddie revealed that promoting the series has been the most ‘fun’ part as the pair finally get to ‘hang out and spend time together’.
Revealing that they barely saw each other during filming, Eddie said: ‘Even though Lashana and I are in it (the series) we barely got to see each other while we were making it.’
‘Because it was kind of a cat and mouse story and we’re kept apart for a huge amount of it.’

The actor joined his pregnant co-star at the BBC Studios to discuss their role in the thriller series The Day of the Jackal
He confessed: ‘So, the promoting (side) has been the fun bit because we got to hang out and spend time together.’
Lashana agreed with Eddie’s statement by saying: ‘It really is, being producers on the show as well, we’ve had a year of chatting about every nook and cranny of the show,’
‘We’ve seen everything, every edit and every juncture of this process, and it’s just been really lovely getting to know each other in that way.’
Eddie also revealed to the radio host why he decided to take part in the new series which is a modern version of the original movie and book.
Revealing he was hesitant to star in it at first, Eddie said: ‘I kind of loved the original movie and the book growing up,’
‘So, when the scripts arrived in my inbox there was a massive amount of trepidation because you don’t want to butcher something that you love.’
Confessing that he changed his mind once he saw the script, he added: ‘(The script) had basically been updated to now, and the scripts were just so propulsive and it felt completely fresh and new.’
‘But it retained the DNA of what was so wonderful in the original, this kind of cat and mouse quality, and the fact that Jackal is basically a chameleon who shapeshifts, you never quite (know) what you’re gonna get.’

As the pair arrived at the studio in London, Eddie cut a casual figure in a beige jumper which boasted a brown and cream striped panel at the chest.
He teamed the jumper with a pair of blue denim jeans and sported a pair of casual black-and-white trainers.
Meanwhile, his co-star Lashana looked radiant as she showed off her blossoming baby bump in a grey dress.
She teamed the dress with a cream coat and sported a pair of comfy ballet flats as she entered the studio.
Lashana plays the role of Bianca in the series, which is an adaptation of a novel of the same name by Frederick Forsythe.
Per an IMDB synopsis, the show charts ‘a manhunt taking place for a dangerous elusive assassin known only as the Jackal’.
Eddie plays the deadly Jackal, with Lashana’s character leading the search to discover his identity.

Ahead of the show’s release, the No Time To Die star opened up about playing Bianca to Entertainment Weekly last month.
She explained: ‘She is so determined to be this strange version of human superhero. And I say strange version because it’s all the twisted elements of things that you would hope that a human wouldn’t do when doing good for the world.’
‘The way that she goes about her work means that there has to be a fall off and a sacrifice somewhere. And unfortunately for her, that sacrifice and the racking of the brain is worth it.’
In regards to both her character and Jackal, Lashana added: ‘People working for good and people working for bad can have such similarities. At the end of the day, they both just have jobs to do.’
