Now, this is a tough one. The Great Escape is one of the greatest films of all time, and Steve McQueen is a legend among men.

But let’s be honest, how many times has your dad made you watch it? Twelve times? 100? It tends to lose its suspense after that.

The Motorcycle Diaries, meanwhile, follows a 23-year-old Che Guevara as he sets off on an adventure around South America on a motorbike, while learning about the true poverty afflicting his continent. It received a standing ovation at the Sundance Film Festival. How many times have you watched it? Once, if that.

Which should I watch? The Motorcycle Diaries, but we’ll allow you to whistle along to the theme of The Great Escape while you watch it.
