Arguably the most entertaining film to come out of Canada last year, Metal: A Headbanger’s Journey is a fast-paced and often very funny look at heavy metal through the eyes of not-quite-reformed headbanger Sam Dunn (who co-directed along with Scot McFadyen and Jessica Joy Wise). The filmmakers copped interviews with an amazing number of metal luminaries, from Tony Iommi to Dee Snider to Alice Cooper. The movie’s only major problem is that despite an admirable effort at comprehensiveness, in 98 minutes there’s only so much ground you can cover. Which is why this week’s DVD release is so welcome—Metal comes in a two-disc set featuring 16 extended interviews, director’s commentary and an additional mini-documentary on the Norwegian Black Metal scene, a fascinating subject the original movie could have spent some more time with.

Also packed with gnarly dudes, but in a somewhat different context, is the classic WWII men-on-a-mission flick The Dirty Dozen. The movie’s being re-released as part of a two-disc special edition featuring an introduction by Ernest Borgnine, Operation Dirty Dozen (a vintage featurette) and the 1985 TV-movie sequel The Dirty Dozen: The Next Mission. —MARK SLUTSKY
