In Elizia's reception room, there are 6 male prisoners, 6 female, plus Beron and Roy Marsden

There are an additional 3 male prisoners in Cell Block 3 (Jelto, Angus MacInnes; Kinano, Arthur White and Garth, Peter Brayham).

On the Entra surface, we see Del Baker (hunted at the start), Phirly (Geoffrey Greenhill, wearing Koenig's clothes), plus 3 male prisoners and 3 female (all also seen in the reception room).

That's a total of 19 prisoners, and 11 prison staff including 7 guards.

Alphan prisoners

Koenig is not the only Alphan prisoner; several other Alphans are also prisoners on Entra.

Ian Flint, a medic

Alan Harris, Alphan

"Beron" is another Alphan medic, actor unknown.

Jane Henley (nurse).
Beron, noted above.
Mercedes Burleigh, not an Alphan but a Darian in Mission of the Darians
Mary Burleigh (Alphan)

On the left, James Muir was a Darian survivor and an Alphan medic in the last episode, Dorxak.

In the centre, David Atkin is an Alphan in The Immunity Syndrome.

On the right, Barry Summerford

"Garth" is played by Peter Brayham, a security guard

One of the guards is also an Alphan. Felicity York, the tower guard, was in Catacombs of the Moon in pink dress (with Nova Llewellyn, the blonde on the left)

This dead body on Ellna has heavy make-up, but it could be the red-haired woman often seen in Command Center and as a nurse.

Guards

Beulah Hughes, Vida Taylor and stuntwoman Cyd Child are brunette; the other guards are blonde (or at least have blonde ponytails).

Stuntwoman Cyd Child also appears as guard 7 during the chase.

A number of publicity photos were taken in the Pinewood gardens of Beulah Hughes and Vilma Riley (see London Evening News, 18 November 1976)
