Had Frank Marshall found bigger stars than Dylan Walsh and Laura Linney (at the time), this would be widely considered a classic today. Ernie Hudson and Tim Curry are high-quality supporting cast. And who can forget Delroy Lindo's sesame seed cake line? Grade-A B-movie.
I wish Frank Marshall would direct more films. While I've enjoyed many of the movies he produced, the few movies he directed have a unique charm to them.
