Zoe Saldana thinks cinema should always “push the limits”.

The 33-year-old Hollywood star has appeared in some of the biggest movies of recent years, such as James Cameron's worldwide smash Avatar and J.J. Abrams’ Star Trek.

Zoe was thrilled to appear in the sci-fi hits, and normally gravitates towards futuristic cinema rather than the average romantic comedy.

"Kill Bill, Alien, Die Hard, Blade Runner, The Matrix, Inception... I like movies which set the tone and which challenge the technology previous pictures had allowed,” she told France’s L'Express when asked about her favourite movies.

“I like movies which push the limits. One of my last crushes was Scott Pilgrim. I could discuss action films for hours because those are the only films that I watch. My mother and my sisters are always bugging me to go and watch a rom com...But I find it boring.”

Zoe also discussed her cinema heroines. The actress is thankful older movie stars such as Jane Fonda and Sigourney Weaver paved the way for strong females in Hollywood.

"Jane Fonda, Pam Grier, Demi Moore, Sigourney Weaver, Linda Hamilton, Patricia Arquette in True Romance... I will be forever grateful to them. They opened the doors. Actresses like Angelina Jolie or I wouldn't be here today without them,” she added.
