Olga Kurylenko claims the effects used in 'Oblivion' were like ''sitting in a washing machine''.

The Ukrainian beauty stars opposite Tom Cruise in the sci-fi action film and while she enjoyed working on the movie, she struggled to get to grips with the 'bubbleship' crafts they used.

She said: ''We had this bubbleship prototype. The cockpit was suspended on a crane and it could be rotated to simulate the nosedives you see in the film.

''It felt as if you were sitting in a washing machine on the spin cycle. It took me a month of training to finally stop feeling sick.''

Olga enjoyed working with Tom, praising him as the ''consummate professional'' because he gets so involved in his movies.

She told Red Bulletin magazine: ''Tom is the consummate professional. He doesn't just come onto the set and act. He discusses every single scene, right down to the finest details. We sat down at a table before we started filming and ploughed our way through the script.

''Both of us had the opportunity to make suggestions regarding our characters or to improve the dialogue. Tom is very conscientious about his work and he expects the same commitment from the people he's working with.''
