TORONTO -- Oscar-winning British star Helen Mirren touted the timeliness of her military drama "Eye in the Sky" as it arrived at the Toronto International Film Festival.

The suspense tale, about a British-led drone mission in Nairobi, made its world premiere at the fest less than a month after U.K. forces used a drone to kill three Islamic State fighters in Syria, including two Britons.

Gavin Hood ("Tsotsi") directed the script by Guy Hibbert.

"I do think it's urgent because the whole business of drone warfare is such a burgeoning way of fighting war," said Mirren.

"This is happening in our name and what I'm so proud about the movie -- about Gavin's way of approaching the subject -- is it's so nuanced; that the morality in that story, any one of us would sit here going: 'I don't know. I don't know what to do."'

In "Eye in the Sky," a planned drone strike against a Somali terrorist group becomes complicated when an innocent young girl enters the scene.

Cameras follow the agonizing debate as military and political officials consider the possible collateral damage, legal ramifications and propaganda effects.

Mirren plays a colonel in a cast that also includes Aaron Paul, Alan Rickman and Iain Glen.

"I think that this film deals with all those difficult, difficult issues and I think it does it with great intelligence," said the four-time Oscar nominee, who won the golden statuette for "The Queen."

"It just throws up the questions for us, and I think as we are committing ourselves to drone warfare -- all of us, we are, it's happening -- I think it's incumbent upon us to ask those questions and consider them."
