Abbie Cornish has said that she often felt intimidated aroundMadonna on the set of W.E.
The Sucker Punch actress revealed that W.E. director Madonna often took her to task when it came to her knowledge about current events when the cameras stopped rolling.
Cornish explained: "You need to be totally switched on to the news and current affairs to talk to her - she asks you questions all the time and expects you to be up on everything that's going on, from Libya to the latest advances in technology."
However, the 29-year-old added that Madonna knew how to unwind at the end of the day, saying: "Standing next to her after a day's shoot and drinking a Cosmo - I mean, it doesn't get better than that."
W.E. will premiere at the Venice Film Festival later this month and will also screen at the Toronto Film Festival in September.
Cornish has previously told Digital Spy that Madonna is "definitely determined and quite a visionary".
