James Marsden doesn't feel like a proper actor.

The 41-year-old admitted that he feels insecure about his acting ability and continues to fear he will not be able to find work, despite having a career spanning more than 20 years.

The 'Butler' star told Hull Daily Mail newspaper: ''I still feel like I'm kind of faking my way through it.

''I think one of the common neuroses of being an actor is you feel like your next job is going to be your last job,''

The father-of-three earned his stripes appearing in 'Zoolander' and 'X-Men', but is most well known for his roles in romantic drama 'The Notebook' and flamboyant musical 'Hairspray'.

But the actor - who has also recently embarked on a music career - has now learnt to reassure himself of his capacity to perform.

He continued: ''Now I actually feel like, 'OK, you've been doing this for 20 years, you understand the business, you understand the technical aspects of being on set, you know what's required of you and where your strengths and weaknesses are. OK, you'll keep working'.''

And it seems that he's enjoying his career path even more as he gets older, despite being uncertain about his future in the industry, stating that he finds the roles to be far more intriguing than those he was offered as a youngster.

He explained:''The older you get, the more interesting the roles are. When you're young, you're playing the Romeo and Juliet and it's all love-driven and hearts coming out of your eyes.

''When you're older, there's more complexity to the way you show love, and what's carried with that, and there's a pain behind it sometimes.''
