She’s an incredible woman, amazing mother and producer and actress and all of these things. Peter Capaldi has heaped praise on his wife, Elaine Collins, for helping him navigate the cut-throat acting industry The pair met in 1983, before marrying in 1991. They went on to have a daughter and are now grandparents’I don’t want to go into it in huge detail because I also have a private life but she’s the person who changed everything for me because she took me in at a time when I wasn’t in great shape, and loved me. ‘Ironically for someone who’s had such an embarrassment of riches, great luck and good fortune, I developed quite a kind of lack of confidence, applying limitations to myself that were not necessary, when I was probably about 26, 27.’He continued: ‘People think the first automatic characteristic of an actor would be that they were full of confidence. ‘I know many actors who are genuinely insecure because the business is so volatile and you can be ditched by it very quickly. ‘And you have no control over it. One of the things that happened to me was that I decided that I wasn’t really very clever or very smart or that I should limit my ambition.’Mr Capaldi, who said he suffered a type of ‘imposter syndrome’ at the time, added: ‘She began to say to me, “No you must think more of yourself. You must work harder and take bigger risks and read more.”‘It’s funny, because people come in to our house, and say, “Oh, you’re so well read, Peter” and I say, “That’s not my books, they’re Elaine’s.” Mr Capaldi says without Ms Collins his acting career in movies like Local Hero and Dangerous Liaisons wouldn’t ever have been possible’And of course, during one of my down periods, which went on for quite a while, we were really struggling financially. ‘But she decided when we had a particularly difficult year, and I wasn’t bringing in any money, that she had to do something. And she asked around and got a job through the BBC reading scripts…”…So she would read scripts and she’d get paid. I don’t know how much, 25 quid or something like that. Elaine took it very seriously and also was very fast so began to earn more money.’And the BBC noticed and said, “This person is really good at doing this. Shall we invite her to apply for a job as a drama assistant?” That was really a job that largely someone who had just come from Oxford or Cambridge would normally get. And she applied, she got the job.’He added: ‘Although that wasn’t a lot of money, it was a regular wage and it allowed me to say, “Okay, well, I don’t have to do this job or that job. I can make a choice about which one I think is artier or better or a job that would help me more.” It gave me the power of veto.’
