Considering there hasn't been a Christopher Lee movie included in the Canon yet, I'd be interested in hearing what Devin and Amy think of The Wicker Man especially considering Lee always cited it as his favorite performance.
It's frequently hailed as one of the most iconic cult films and I think it'd be a worthy addition to the Canon. The performances from Edward Woodward and Lee are fantastic and the film does a wonderful job at creating a sense of dread contrasted with the bright, cheerful atmosphere of Summerisle. One of the things I love about the film too is that it's not relegated to one specific genre. It's often labeled as a horror film but it's also part mystery, thriller, and even musical with a variety of strange and memorable numbers.
Without spoiling anything, it also features an iconic twist that stays with the viewer long after the fact in my opinion. Whenever I see a list featuring the scariest films ever made, this often makes the cut and rightfully so. I don't think I've ever heard Devin or Amy mention it before so I'd be curious as to what they make of it since it is a strange film.
