You can't buy tickets without an adult on your website, which is why I was told to try on the phone. I'm not sure your staff member knew the rules.

1. Dr Gorst Who else? Joshua James is on screen for a matter of minutes, even counting his haunting of Bix’s dreams, but his puppyishly eager explanation of the appalling interrogation method he has helped devise is very genuinely unsettling.

2. Ulaf This ageing and ailing prisoner on the brink of release – they all believe – is raging against his own dying light, angrily insisting he can work as hard anyone amid increasing confusion. A deeply moving performance by Christopher Fairbank.

3. Supervisor Lagret Easy to miss, but a quietly brilliant performance from Michael Jenn as the ISB lifer who ducks out of the in-office drama to get on with his job but, in a brief and truly wonderful scene, shows humanity for the stricken Major Partagaz.

4. Chief Hyne This bored corporate manager just wants solid results for the regional meeting. He mistrusts Syril’s re-tailored uniform and needs a convenient story for the deaths of Kravas & Verlo: “Nothing too heroic. We don’t need a parade.” A masterclass from Rupert Vansittart

5. Clem Andor From first glimpse, as Maarva dismisses his worries about arriving Empire forces – “Well in that case, by all means, let’s power forward” – Gary Beadle imbues Andor’s adoptive dad with a beguiling mix of playfulness & charisma. Truly a step-dad you’d want to avenge.

6. Erskin Semaj The political aide real political aides dream of being. An utterly efficient factotum to Mon Mothma while also spying on her, he is quick witted enough to save the day in Mothma’s rescue, even when it's fairly clear it’s the first time he’s ever held a blaster.

7. Sgt Linus Mosk Alex Ferns, another actor who has had more roles than you’d had hot dinners, gives a masterful performance as a corporate-military functionary who is so zealous that at times even Syril worries he’s taking the piss. Mosk is not. He is deadly serious.

8. The patient Look, it’s not a role. As far as I can see it’s not even credited to an actor. But what a cameo.

9. Kravas and Verlo “Oh, that is a hard look for a little thing like you.” Minutes into ep 1 and Lee Boardman’s makes the viewer know they are in safe hands. He & Stephen Wight’s Milo are the pettiest of petty bullies, who don’t even work for the Empire, just an outsourced arms.

10. Capt Kaido Much of what Jonjo O’Neill does in Andor involves staring into the middle distance and looking quietly satisfied. But boy, does he do it well. A tiny but vital role – the captain supposedly subservient to Dedra, but who makes it very plain he is in complete charge.

11. Thela “Rebellions are built on hope.” Stefan Crepon’s wide-eyed but utterly realistic hotel clerk delivers one of the series key lines. But from his first appearance, Crepon makes this gentle insurgent insistently compelling.

12. Lt Krole “The good news is, Alex, you’ve got a role. The bad news? Well, read the script.” Another mini-part which in less careful hands could have been a disaster. Shakespeare veteran Alex Waldmann gets Krole’s mix of hideous entitlement and wheedling neediness just right.

13. Niya “If I die tonight, was it worth it?” A beautifully moving line which, in the wrong hands, could be mawkish. But Rachelle Diedericks completely nails this empire-debutante’s heady mix of excitement, terror and intense responsibility.

14. Captain Elk Another beautifully crafted vignette, a commander almost bored by empire power. The look given by Roger Barclay, who actually attended the Sandhurst army officer academy – after Luthen’s craft vanishes, leaving a trail of destroyed Tie fighters, is exquisite.

15. Dr Rhasiv Also fitting a lot into a tiny amount of time was Adrian Rawlins, aka Harry Potter’s dad from the films, whose imprisoned medic desperately quashes any empathy for patients he knows can never leave.

16. Commandant Beehaz Speaking of great Aldhani characters, everything from his unwillingness to learn the local language to a dress uniform belt that has “shrunk” gives a vivid picture of the arrogant complacency of this garrison commander and empire functionary.

17. Lt Gorn Seven years on Aldhani would be enough to test anyone, and Sule Rimi utterly humanises what could be a walk-on part – the veteran turned to rebellion after the empire killed his love interest, a local woman.

18. Beska The most glamorous and brutal of ISB agents, even if she was eventually and fatally outwitted by a political aide yelling nonsense at her. Romanian actor Ana Ularu *totally* rocks the look.

19. Birnok and Taga You could pick any one or two from a dozen of the prisoners, but Rasak Kukoyi and Tom Reed are ridiculously watchable every time they appear.
