Nicole Kidman stopped Naomi Watts from giving up her acting dreams.
Watts, 44 and 45-year-old Kidman have been friends since working together on the movie Flirting in 1991.
When Kidman's Hollywood career took off, she urged Watts not to give up.
Speaking on CBS' Sunday Morning, Naomi said: "She kept saying, 'It's just going to take one thing, one thing, Nay, and you know, if you're in a hit film...then everything changes.'
"Oh my God, I mean, I considered myself fairly sensitive, but I don't think a strong person could cope with [rejection] over and over again. There were moments when I was sure I was done. Oh yeah, but I didn't have a plan B really, I didn't."
