Cooper Reveals How Zoe Saldana Changed 'Words'

The upcoming film The Words is based on the aftermath of a writer's plagiarism, but there is also a love story that encompasses the plot between Bradley Cooper's and Zoe Saldana's characters. As Cooper told ET at the premiere, the love story wasn't originally planned to be as prominent in the script.

"Zoe Saldana brought so much to the movie and a depth to it that we didn't really bargain for," Cooper said. "Because of that, the movie became very romantic...The storyline between Rory (Cooper's character) and what he was going to do meant so much more because you really felt the love between Rory and Dora (Saldana's character)."

Cooper, who briefly dated his love interest in the film in 2011, attributes the film's depth to Saldana's acting skills, saying that it "just kind of changed everything and made it a much deeper movie."

Amid the frequent songs of her praise, Saldana said that she was humbled to receive such flattering comments from her co-star as well as writers and directors Brian Klugman and Lee Sternthal.

"I give 110 percent for anything that I sign on, whether I had to work for it or it was offered to me," she asserted. "The least that I can do is fully commit to it."

The 34-year-old actress, who rose to fame for her roles in Star Trek and Avatar, turned the spotlight back on those who had complimented her and thanked them for their flexibility in giving her creative space on the project.

"When I read the script, I was very taken by it. All the characters were so complex and very textured and they were very human," Saldana said. "I was really excited, and every day I was coming on set with ideas, and as an actor, you feel very present and very relevant when your ideas are taken into high consideration--especially as a woman--so, these are stellar men."
