I was looking for something new to watch and happened to stumble across a Witchblade movie and TV series.
Are the film and series completely separate, or is the film a lead-in into the TV series?
Will I spoil anything by watching the film followed by the series?
If the movie you refer to is this, and the TV series is this, then yes they're connected. The movie is just the pilot of the series, and as such should be watched before starting the series. Wiki source
On the other hand, if you're referring to the unrelated anime, as far as I know, that's not linked to any movie.
