Colin Farrell feared he was ''unhireable'' due to his battles with drink and drugs.
The 37-year-old actor claims entering rehab for addiction to recreational drugs and painkillers in December 2005 helped salvage his burgeoning Hollywood career as he worried producers wouldn't want to hire him because of his hard-partying lifestyle.
Following his sobering experience in rehab, the Irish star has gone on to enjoy critical acclaim in movies such as 'Saving Mr. Banks', but he says the greatest joys in his life are his two sons James, 10, and four-year-old Henry.
Quizzed about his approach to parenting, he said: ''Be present. Just run up and take it from there. My sons are fairly well behaved ... I don't know if that's a testament to me or them but they're lovely young fellas.
While he may be one of the most recognisable stars in the world, Colin insists he doesn't care about fame, which he feels is simply a ''by-product'' of his acting work, but he accepts notoriety is part of his job.
