The Person of Interest actress revealed that while she has found considerable success thus far, she still wonders whether she will continue to be able to book new roles.
"Every actor - I don't care how long they've been in the business - worries. That fear of 'When is the phone going to stop ringing?' But I don't suspect it will ever stop ringing. I'm going to be like Betty White. I'm going to work for as long as I want to," Henson explained to The Huffington Post.
"I'm just getting started. I still haven't done theater yet. It's funny, my audience is a wide range of people: Kids from Karate Kid and then I have a mature crowd from Benjamin Button. I have a cult following because of Baby Boy, my very first film. They play it a lot on the channels that play videos. It's a really interesting mix and I love it."
Henson also said that while she finds it hard to balance her career with being a mother, she enjoys the contrast of the experiences.
"It's difficult but such is life. It comes with challenges but at the same time I love being a mother. It's the best part of my life," she explained.
"It enriches my life so much. It gives me other things to think about besides this crazy industry that I decided to partake in. It keeps me grounded and focused on what life is really about."
