at the start of his career

Speaking on Sean Hayes' 'Smartness' podcast, the Hollywood star

explained: "I definitely did feel, moving to Los Angeles for 'Alias', like I was back in high school.

"I couldn't get into any clubs, no girl wanted to look at me ... I was just totally depressed."

Bradley spent five years on the show. But he went through a tough time after he was written out of 'Alias' and he sustained a nasty Achilles tendon injury while playing basketball.

However, work later picked up and he eventually landed a career-changing role in the 2009 comedy movie 'The Hangover', which propelled him to global stardom and helped to make him to become one of the most sought-after actors in the movie business.

Bradley didn't experience fame properly until he was in his 30s and he appreciated his success more because he was a bit older.

He said on the podcast: "I did have the benefit of that happening when I was 29 ... I got to do go through all of those things before fame even played into my existence on a daily level ... I definitely made major breakthroughs from 29 to 34, where I was at least able to stand in front of somebody and breathe, listen and talk."
