Here's who everyone is, with a note if more than one actor plays them as happens in at least 3 cases!
MEN
Lieutenant Scott James Warwick 1-4WOMEN
Walters Steve Morley
Second Trooper (Carter) Mark Straker
Collis Kevin O’Brien
Jones Miles Ross
Brooks Steve Whyment
Marshall (location) Ian Ellis
Marshall (studio) Jonathan Evans 1-4
Sergeant Mitchell Ann HollowaySo which trooper is which and played by who in the program? We'll start with the easy ones:
Snyder Suzi Arden
Bane Anne Clements
Seaton (Location & Studio Day 1) Lisa Clifton
Seaton (Studio Day 2) Mary Eveleigh
Bailey (Location & Studio Day 1) Linda French
Bailey (Studio Day 2) Jennie Persiva
Foster Lynne Brotchie 1-2
Lieutenant Scott played by James Warwick, who survives!
Sergeant Mitchell played by Ann Holloway. She dies towards the end of the episodes in a search party with Troopers Carter & Bailey.
Walters, Steve Morley, and Snyder, Suzi Arden, are left on the surface.
Snyder later descends into the tunnel to meet the injured party and is killed there.
Bane (in the credits as First Trooper) is played by Anne Clements. She's the trooper that falls and injures her shoulder and is forced to return to the surface.
Collis, Kevin O’Brien, is the trooper who accompanies her and they're killed together.
We get a clear glimpse of Collis earlier in the episode walking through the tunnel. His badge is discernable on the Blu Ray version,
Carter (in the credits as Second Trooper) is played by Mark Straker. He's one of Mitchell's search party and gets to speak.
Carter too is seen clearly in the walking through the tunnel sequence. You can see enough of his badge to be sure who he is.
The other member of the search party is Bailey
On Location & Studio Day 1 she was played by Linda French.
In Studio Day 2 she was played by Jennie Persiva.
I've no way of telling which actress performed the search party scene!
Onto the later episodes. Three troopers survive the caves.
Te surviving female trooper is played by Nikki Dunsford who I think has her name spelt wrong on IMDB. Nice clear shot of her from episode 4. She's playing Austin, who's the other trooper who isn't named in dialogue and we don't see her name badge in any of the four episodes.
Brooks is played by Steve Whyment.
He is noticably absent from the Tardis scenes in episodes 2 & 4, to the point of causing a continuity error when is grabbed by a Cyberman at the rear of the party entering the Tardis.
Brooks goes with Scott to the bridge while Marshall is left guarding the stairs but cofusingly when we see the stairs being guarded it's Brooks while Marshall helps shift crates. Marshall is then killed off screen and Brooks escapes the frieghter in the escape pod.
On Location Marshall is played by Ian Ellis.
The production subs on the Blu Ray say he failed to show up for his make up tests and was replaced by Marshall (studio) Jonathan Evans who you can see with Austin, in the Tardis in episodes 2 & 4, and on the freigter in 4:
So that's 11 out of 14 troopers found!
The three unaccounted for names all perish off screen.
Jones, the other trooper unnamed in the dialogue, and Seaton die in a cut scene at the opening of the battle with the Androids. Their remains & guns are seen on the floor of the cave.
Seaton had been mentioned in dialogue when she and Foster, who seems to survive episode 1 only to be killed in another cut scene early in episode 2.
So the three we're really looking for are
Jones Miles RossWe also need to sort out which Bailey is which, even though we've spotted one of her above:Seaton (Location & Studio Day 1) Lisa Clifton
Seaton (Studio Day 2) Mary Eveleigh
Foster Lynne Brotchie 1-2[F:1]
On Location & Studio Day 1 she was played by Linda French.There's a parade of faces past the camera during episode 1 most of which I can't identify:
In Studio Day 2 she was played by Jennie Persiva.
ONE might be Sgt Mitchell.
TWO
THREE is this Marshall in the studio?
FOUR or is this Marshall in the studio? Both chaps look a little like him!
FIVE is this Bane?
SIX - This is Collis
SEVEN
EIGHT - This is Carter
Plus there's this female Trooper between Kyle & Mitchell on location:
The only other shot of Troopers on location where you get clear views of the faces I'm pretty sure we can identify: Carter o the left and Collis on the right:
So who are the unidentified faces above?
