Where's Marlowe? (1998)

After making a 3-hour fiasco about New York City's water supply, a two-man film crew decides to take it up a notch by documenting life in the private investigator offices of "Boone and Murphy". Cheating husbands and missing dogs fail to bring in the big bucks however, and after sleeping with the wife of one of their clients Murphy leaves. To stop Boone from having to close down the business the two film-makers must resort to a hands-on approach in the investigations to ensure the completion of their movie.
