‘I always feel slightly sick when I hear actors talking politics,’ says Robert Carlyle — that polished Glaswegian burr sounding no less arresting over a slightly patchy Zoom connection. ‘I mean we’re all entitled to an opinion,’ he continues, sounding for a second as though he might be about to opt for a more diplomatic track. ‘I just find that too many actors find it difficult to get theirs across without sounding like a twat.’ It’s a fair point, you might think. But for Carlyle, it’s also been a good professional move. Reflecting on his career, he credits this aversion to mouthing off with inspiring his long-term commitment to keeping his head down. Not only, he says, has this helped him maintain the healthy mystique necessary for a serious actor, but it’s also stopped him from stumbling clumsily into public debates.
