“A huge, brilliantly made film with rich characters and huge suspense,” as the actor rightly describes, Jaws is still seen as the greatest shark movie ever made, even almost half a century since its release.

“Harvey I’ve always loved because Jimmy Stewart’s one of my all time favourite actors,” McGregor says of his fourth pick, a comedy-drama following a middle-aged man who has a six-foot-tall rabbit for a best friend.

Describing the film starring Hopper, Jack Nicholson and Peter Fonda as “very cool,” Easy Rider also holds a special place in McGregor’s heart due to his fondness of motorcycles.

“It’s like a master class in how to shoot and act and light and it makes me very depressed watching it, because we don’t make films like that any more — and I wish we did”.

“I just think it is a really incredibly made film — made by John Boorman, who was an incredible director,” McGregor explained, adding, “I just think it’s a film where you kind of get into the heart and soul of these people and it unsettles you”.
