gwïon morris jones as captain mark v. wilson (credited as second lieutenant, but it’s the only mark wilson to choose from)
ian hughes as michael flynn (idk who michael flynn is. searching him just gets a very clearly unrelated michael flynn. currently a mystery, this one)
jakob diehl as sergeant william “popeye” stranghöner (couldn’t find a longer bio for him, but he was a guard at stalag iii. you can read some about him here, here, and here (click the ocr text link and search for “popeye”))
robert hands as major gustav simoleit (another stalag iii guard)
as for the rest, it’s a tossup btwn small roles and other mysteries. léonie lojkine is in an unknown role, joshua rogers is playing an hq orderly, paul hunter has an unknown role, joshua lay is playing a dancer, tommy tweedy as a scottish senior officer, jack bennett in an unknown role, and taraash mehrotra in an unknown role. rahshan wall is likely to be in the show as well given the number of confirmed actors are in the show.
nancy farino is now confirmed to be playing a recurring character named “audrey”. similarly to the previous female roles, there’s no surname added to the role. if this is a made-up character, this’ll just end up a moot point, but if it’s a real person, i’m leaning towards her being audrey herres (the wife of ferdinand herres, a captain in the 100th. but i could also be totally wrong here). @carninator-blog thinks it’s likely an audrey was mentioned in harry crosby’s book, but neither of us currently have it on us to check
