THR reports that Sheen will play Roland Blum, "a brilliant, charismatic and Machiavellian lawyer" - aren't they always - who has a lust for drugs, sex and winning at all costs. Again, who doesn't?
Sheen joins 'Game of Thrones' alum Rose Leslie, 'The Good Wife' stars Christine Baranski, Cush Jumbo and Sarah Steele, Delroy Lindo (remember him?) and 'Beauty and the Beast' star Audra McDonald.
This isn't Sheen's first foray into television, having done four seasons on 'Masters Of Sex' with Lizzy Caplan.
'The Good Fight' airs on RTE 2 here in Ireland.
