The Spierig bros. went to their butcher and bought rotten chicken and pig guts to enhance the effects.

There are 305 visual effects shots in Undead. The Spierigs did 95% of them on their home PCs.

This film only cost about $1 million Aust., but it looks like it cost much more. The Spierig brothers would go to their rubbish tip and just get everything they needed. Down here in Australia, you can just waltz in, grab what you need, and go out without paying.
