Halle Berry ''didn't see'' her family while shooting the first season of 'Extant'.

The Oscar winner admits she was surprised by how much harder filming a TV show is compared to films and struggled to find time to hang out with husband Olivier Martinez, their son Maceo, 20 months, and her daughter Nahla, seven, who she has with ex-boyfriend Gabriel Aubry.

She said: ''I thought, I'm going to go into TV, be at home with my family. [But] I didn't see my family, and I never worked harder in my life!''

The 48-year-old beauty was determined to continue breast-feeding her little boy despite spending long days on set.

She said: ''I was doing drive-by nursings every two hours. I was in over my head - the amount of scenes we shoot in a day!''

But Halle says filming the upcoming second season of the show was much easier and she has learned how to have a work-life balance.

She said: ''I got it down.''

The 'Monster's Ball' actress is a big fan of sci-fi and thinks aliens exist.

She said: ''I do believe there's something else out there. I'm not so egotistical to think that we're the only ones in this vast universe.''
