Vetril Dease

They don't say so in the movie, but his name is an anagram for DEVIL EATERS. Morf Vandewalt and Imeldus Vanderhorst are odd names too, but I haven't been able to rearrange them into any phrases. I figure they're just parodies of the kind of names artists have, as the movie itself is a satire of that ridiculous class of people who create and buy and sell high art. But still, maybe someone out there can crack the code if it's there. I did find DEMON in both names. Interesting coincidence given [spoiler]Morf's fate[/spoiler].
