One of the last films worked on by the late Alan Rickman will premiere in London on Monday.

His co-star and long-time friend, Dame Helen Mirren, will be among the stars at the red carpet event in Mayfair.

Thriller Eye In The Sky sees the 70-year-old as Colonel Katherine Powell, a woman in command of a top secret drone operation to capture terrorists in Kenya. Through remote surveillance and on-the-ground intelligence, Powell discovers the targets are planning a suicide bombing and the mission escalates.

But as American pilot Steve Watts (Aaron Paul from Breaking Bad) is about to engage, a nine-year old girl enters the kill zone, triggering an international dispute which reaches the highest levels of the US and British government.

Alan, who died in January from cancer aged 69, co-stars as Lieutenant General Frank Benson.

“What I love about the film is that it’s Alan as I knew Alan – a brilliant character actor, funny, urbane, intelligent and very human. It’s really great to see him up there,” Helen said on The Graham Norton Show.

Oscar-winning actor Colin Firth has produced the film, which is directed by Gavin Hood.

The South African film-maker has also been at the helm of blockbusters such as X-Men Origins: Wolverine and Ender’s Game.

Eye In The Sky is released in UK cinemas on Friday.
