Rihanna is keen to appear in more movies.

The 24-year-old singer made her acting debut in sci-fi movie 'Battleship' earlier this year and she now wants to take up more roles on the big screen after ''really enjoying'' the experience, but she doesn't have any parts set in stone just yet.

She said: ''You can't plan for anything, the unknown really. I hadn't done anything in acting so I didn't feel like it was appropriate to have any plan.

''I didn't know if I would like it or be good at it. I really enjoyed the experience and I want to do more, try different types of roles so that I can see what I excel in most or like best.''

Rihanna watched ''a lot of bad bitches'' to gain inspiration for her role of no-nonsense Petty Officer Cora ''Weps'' Raikes in 'Battleship'.

She added to MTV News: ''There were a few - I won't name them, but there were a few. [They were] mostly actresses I looked to and looked up to and embodied their characters and tried to see how they would approach the action. I watched a lot of bad bitches.''
