The third season of Alex Rider will debut on Amazon Freevee on April 5 and the show's stars Otto Farrant and Vicky McClure have opened up about its challenges and highlights.

During a recent interview they discussed their favorite parts of filming this series and Otto Farrant described it as the "best yet":

"I think this is the best season yet to be honest. In terms of action, with pretty much every single episode, we've got an action set piece, sort of on the edge of your seats moment. And if I were to pick some highlights, I mean, we filmed in Malta!"

"We've shot this show over five years. And in that time, we've had a pandemic, so we couldn't go away. You know, we did Amsterdam in Lincolnshire. We did Romania at the beginning of the season, but it was so nice to go to Malta and its expansive landscapes with the sun setting, and it just makes that show feel so much more international and really, really classy as well."

Vicky McClure added that she has numerous personal highlights from filming the third season:

"For me, I love the family feel that this show brings because your mom and dad will enjoy it too. It does teeter on the edge of "the danger is real." And it's not spoon-fed at all. So there is this kind of concentration that you need to keep up with the plot."

"And yet, there are really beautiful friendships that you know, are so important and probably the driving force of the whole show because Alex is, is a good guy. He's got a kind heart. He's morally sound, it's a good message to be sending out to youngsters, and it's also a fiercely entertaining show. I think having something you can watch as a family that isn't a film or a one-off is great... you can sit and binge and that is wonderful."

The pair were also asked if there were any challenging scenes and both teased that there is one in particular that stands out.

Otto Farrant said: "The great thing about this show is that it is such a challenge. It's such a marathon to run, we shoot over six months, and you're coming up against some heavyweight actors as well, to learn from and also to play with, so it's always challenging."

"But if I were to pick one scene that was really challenging... there's a big scene towards the end of this series, which for anyone who watches it, you'll know what I'm talking about. And it was just trying to bring that to life and make it feel as real as possible. It was a hard thing to do, but I think everyone's going to be really excited."

Vicky McClure then echoed this sentiment, saying: "It was a tricky scene, but with Otto being such a collaborative actor and an executive producer on the show, as well and having a great director, and all those elements, really helped. And that creates something that you weren't expecting and it tends to be quite unique and raw. So hopefully that's come across."
