Rihanna says her role in Battleship is the perfect way to start her acting career.
The singer makes her movie debut in the adaptation of the classic board game of the same name.
She told UGO.com: "After I read the script I was really, really impressed and I wanted to be a part of it. Plus it was a role I felt like I could handle for the first time I'm acting."
However, Rihanna admits she had her doubts about the film, as she had no idea what it was about when she first met director Peter Berg.
She said: "It's weird how it happened, I walked into a meeting, I know I had a meeting, but usually my manager would be there to prep me and say, 'Okay, this is what we're doing, this is who we're meeting, this is why we're doing this meeting' What it's about?
She wasn't there, and I walked in. And Peter Berg just walked out and said, 'Hi, come in' and I'm like, 'Where is Christa, my manager? Where is my manager?'"
Rihanna continued: "She wasn't there, and I walked in and all I saw were these little alien mock-ups, these little dolls. And he just started saying, 'Yeah, these are the thugs, he's a thug.' 'Uhh, okay,' I laughed and then I realised that he wasn't laughing, and I was like, 'This is weird. Why are there pictures of aliens all over this room?' And it was just crazy because he was just really super enthusiastic about it, and he was so sure that I could pull it off and I didn't even know that he was the director of the film, I didn't know anything. I didn't know what I was doing, where I was going, why."
Battleship, which also stars Liam Neeson and Alexander Skarsgard, is due for release on May 18, 2012.
