Jessica Alba insisted on having the 'Machete'script rewritten before agreeing to appear in the film because it was too sexy.
The 29-year-old actress - who stars alongside Denny Trejo, Lindsay Lohan and Robert De Niro in the movie - is not "comfortable" with raunchiness on screen and asked the film's director Robert Rodriguez to alter the storyline because she didn't like it.
She said: "You think this version is sexy? In the original script I played twins, and there was a lot more sex.
"But I've never been very comfortable with that stuff. I get freaked out and nervous, I guess, so I told Robert Rodriguez, 'This is an awesome movie and I'd love to be part of it, but I don't feel comfortable doing that,'and he was like, 'Oh, we'll rewrite it and we'll do what you are comfortable with.'"
Once the 'Machete'script was altered, Jessica was happy to take the role in the film - which tells the tale of a man who goes a brutal rampage against a former boss - though she had to brush up on her Spanish skills.
She said: "It was worse in the beginning and got better towards the end. But I wanted it to be like that and my cadence was very 'gringa'in the beginning. But I'm really trying."
