It seems Joseph recorded a radio play, The Icelandic Journals, for BBC Radio 4 which was broadcast this week. There are four more days to listen again on iPlayer. Sorry I couldn't give more notice to listen, I didn't know about it, and it didnt appear in searches.
At the height of his fame, William Morris (Joseph Millson) left his wife Janey and mentor Rossetti to their affair and headed for Iceland, as ever in pursuit of an answer to the question: how to live? While travelling this starkly dramatic landscape, he kept a journal for his confidante Georgie, the wife of his friend Edward Burne-Jones. The journals are Morris at his best: visually attentive, relishing wonders and noting every good dinner as well as every shift of light and mood. He also writes about what he doesn't know he's feeling: what it means to go away and come back, to be apart and alone. Setting the journals in this context, Lavinia Greenlaw has drawn on the letters and journals of Morris's circle to reimagine the events of that summer.
The music is Debussy's String Quartet in G Minor performed by the Alban Berg Quartet.

Another mystery project called The Beast In The Jungle has also been cast and finished filming, according to this tweet. It doesn't say if this is TV or Film.
#casting & shoot of The Beast in The Jungle is complete. Joseph Millson and Camilla Rutherford play the leads in the Henry James adaptation.
