It is a great movie, and I’m glad they got their fifteen minutes of fame (30 years too late). They even got a tour down here to Australia out of it. Part of the reason the movie worked is because they are such likable, relentlessly optimistic guys.
Truth be told though, their music wasn’t very good. I’ve seen some awesome bands who didn’t make it, or didn’t reach the levels of popularity they should have (Tyketto’s Don’t Come Easy is one of the best hard rock albums I own and yet they are virtually unheard of). Anvil, for mine, aren’t one of them - but I’m pleased for them nonetheless.
I might have to dig the movie out though.
