Sigourney Weaver may have a successful Hollywood career now, but it wasn't always so easy for the brunette actress.

Weaver said that directors hesitated casting her because at six feet she would definitely be taller than some of the other male co-stars, according to the Toronto Sun.

"When I started, hardly anybody wanted to hire a woman who was six feet tall," she said. "Which man wants to spend their shooting days on the set on an apple box just to be able to look into my eyes?"

Another problem Weaver faced was wanting to have a Hollywood career and wanting to be a mother.

"I feels sorry for women like Katharine Hepburn," she said. "She might have won four Academy Awards, but she never got to enjoy what it means to be a mother. I find that very sad."

Weaver was nominated for her role in "Aliens."

In June, she talked about how her life changed after being nominated for the 1986 movie, according to the LA Times.

"After I got the nomination, suddenly, they listened to me very carefully," she said at the Hero Complex Film Festival.

Further proving that she is an in-demand actress, Weaver is going to be in the sequels to "Avatar." Her character, Dr. Grace Augustine, died in the first one, so she will have a new role, notes Deadline.

"Sigourney and I have a long creative history, dating back to 1985 when we made 'Aliens,'" said director James Cameron. "We're good friends who've always worked well together, so it just feels right that she's coming back for the Avatar sequels. Her character of Grace Augustine, as fans know, died in the first movie, so she's playing a different and in many ways more challenging character in the upcoming films. We're both looking forward to this new creative challenge, the latest chapter in our long and continuing collaboration."
