The British actor passed away aged 69 in January (16) after fighting a secret battle with pancreatic cancer, leaving behind an impressive film legacy, including his role as Severus Snape in the Harry Potter franchise, Robin Hood: Prince of Thieves, Die Hard and Sense and Sensibility.

His final film is Eye in the Sky, a thriller which also stars Oscar winner Helen, 70, and the actress believes it is a fitting tribute to Alan's work.

"Alan was a genius character actor and he could play all these amazing baddies," she told Britain's The Andrew Marr Show on Sunday (10Apr16). "The Alan we see on the screen in Eye In The Sky is Alan. It's Alan as I remember him. His wit, his humanity, his intelligence. I think Alan would have been really, really proud for this to have been his last film."

The plotline examines modern warfare, and the movie's director Gavin Hood also recently praised the late actor for introducing many different dimensions to his character Lieutenant General Frank Benson.

“The role of the general could so easily have been played in a fairly stereotypical way, a general with one position and this is his view,” he explained to the Huffington Post. “What Alan brings to a role… is a huge degree of intelligence, humour, irony, wit. He makes you laugh in the film, at moments of extreme tension. He helps the audience just release that tension for a moment, just by a throwaway line. Alan has the ability to play just absolute emotional truth and yet with real humour and never taking it to the slapstick level.

“In many ways, it’s not a flashy role, but he fills it with such nuance and dignity and authority.”
