NEW YORK, Oct. 29 (UPI) -- Christopher Chung says he was surprised to learn his character Roddy Ho would be at the center of the story in Season 5 of Slow Horses, which wraps up Wednesday on Apple TV+.

The screen adaptation of Mick Herron's best-selling novels follows a group of MI-5 rejects, including arrogant computer expert Roddy, who are remanded to the dilapidated Slough House office under the dubious supervision of the disheveled Jackson Lamb (Gary Oldman).

Season 5 sees Roddy over the moon because he has a new girlfriend, however, everyone around him thinks she is too good to be true, especially since someone also seems determined to kill him.

"When we had the cast and crew showing of Season 4, all the heads of department -- hair, make-up, costumes, lighting -- everyone said: 'Oh, have you read the new scripts yet? You're in it heaps. It's going to be your season!'" Chung, 37, told UPI at a recent New York Comic Con press conference.

"So, it was very exciting for a whole of five minutes and then it became quite anxiety-inducing. But, it was great fun. It's nice to be able to take Ho outside of Slough House and see what he's like and unveil another layer to him that I don't think the audience has seen," he said.
