I thought the mix of Euro-accents was a bit odd at first, but the drama's so long I got used to it! I think some of the smaller roles may be dubbed in the Eng Lang version, but 'Danton' and 'Robespierre' had their own voices - I think the latter is a Polish actor (he was in Wajda's 'Danton', too), and Peter Ustinov (Mirabeau)was multilingual, so presumably could do his lines in any language under the sun!
