Sorry to hear about your ‘nuit blanche’, Mme Bertho… Kellie Bright, who used to play Kate, is currently in EastEnders (so I hear) and is on Strictly Come Dancing this season. Also Felicity Jones (to my great shame can’t remember who she played) has gone on to Big Things in Hollywood, hasn’t she?
If I recall correctly, Felicity Jones played Emma Carter. Charles Colingwood has been in many things, including an episode of Inspector Morse. The Archers own Facebook page is helpful on this too.
Michael Cochrane who plays Oliver is in loads of things. He played the dastardly Sir Henry Simmerson in a couple of the Sharpe TV movies. (When Oliver does show up on the Archers I tend to call out “Ain’t you the Simmerson that lost the King’s Colours?” :D)
Recently I’ve spotted him in The Musketeers and Downton Abbey (he’s a small recurring role as the local vicar in Downton. He appeared just a couple of weeks ago performing a marriage ceremony.)
