The Star Trek cast member, who made her acting debut as a dancer in 2005's Centre Stage, revealed that she quit her ballet career as she hated the way it made her feel.
"I had to quit ballet because it felt like a part of me was dying inside," Saldana explained in a new interview with Cosmopolitan For Latinas.
"It takes a lot of courage to face up to things you can't do because we feed ourselves so much denial... In dance you use every part of your body except your voice. I wanted to start acting because I wanted to use my voice."
Saldana also spoke out about the pride she feels due to her half-Puerto Rican, half-Dominican heritage, adding: "People think of Latina women as being fiery and fierce, which is usually true. But I think the quality that so many Latinas possess is strength. I'm very proud to have Latin blood."
She recently signed on to appear in Scott Cooper's Out of the Furnace, as well as upcoming heist film Swindle.
