Where's Marlowe? (1998)

After making a disastrous 3-hour documentary on New York City's water supply, two young filmmakers focus on the goings-on of life in the LA offices of Boone and Murphy, private investigators. 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 filmmakers must resort to a more hands-on approach in the investigations to ensure the completion of their movie.

Unfortunately the movie Where's Marlowe? is not yet available on HBO Max.
