Working with Olivia Colman has probably been the highlight of my career so far.

I watched the night unfold from beginning to end on my own here in my flat in Budapest where I've been working for the last six months, and when it was announced that Barack Obama was indeed president-elect, I wept.

To be on set with Tom Hiddlestone and Hugh Laurie is just fantastic. But during 'Homeland,' I was on set with Claire Danes and Damian Lewis, so I'm used to working with big hitters.

The highlight of my career? The Olympics, of course.

I do know in the 1960s comics, Martian Manhunter took on the form of a black man - that could have been influenced by the political climate back then.

I've been acting for 27 years, and anonymity has always been a part of what I do. Of course you get recognised every now and again, but 'Homeland' pushed me into a completely different strata, and that took me by surprise.
