I won't hold my breath over this. For one thing the first strike against them is casting. Is Depp going to be Kolchak? Right there I think they're off. Kolchak has to seem an unlikely hero including the way he looks. I'm not saying to you have to perfectly mimic Darren McGavin and his manner of dress, but he should look like one of the last people you'd expect to be the hero.
Are they going to camp it like Dark Shadows? That would be stupid as the original work already had its flavour of humour.
Until I hear more I'm presently not interested in this.
