London, Jan 1 (PTI) Actor Lupita Nyong'o says spending time away from family on a film set can be an 'isolating' experience.
The 36-year-old actor, who is fiercely protects her personal life, also said privacy is 'a commodity that is hard to come by'.
'Filming is so time-consuming. And intense. With 'Black Panther', a lot of us were single. On 'Little Monsters', nobody was single.
'Everyone, when they're done with their day's work, wants to go home to their families, which makes a whole lot of sense. When you don't have that it's very isolating,' Nyong'o told British Vogue magazine.
The 'Us' star said she attaches herself to a project when she is 'seduced' by its potential to change the narrative.
'I don't get fulfilment from the number of zeros attached to a project. What I'm seduced by is the potential to shift a narrative. That is very seductive to me, having social and cultural impact,' she said.
'I definitely want to claim ambition, but I get very compulsive about the things I am passionate about, to the point of not sleeping. It's very impractical. I fight the barriers that I form for myself, because they're often ridiculous,' she added.
The Oscar winner, a vocal advocate of women's rights and environment among others, said she speaks up for causes she can 'personally vouch' for.
'There's a lot going on in this world, a lot of causes that are noble. But I feel most useful when I have a personal connection. And the conviction to say something,' Nyong'o added. PTI RDS RDS
