Just when I think I've run out of ideas for the Hollywood Dictionary, I have a conversation with a friend who lives elsewhere...
GREENLIGHT: The traffic rules in Hollywood -- like many other rules in this town -- are somewhere between opposite and weird. Green means Stop. Yellow means Honk. Red means Speed Up. The traffic cam was supposed to rectify this by scaring people into driving normally. It didn't work. [Tip: A jet-propelled car travelling 245 mph does not trigger the traffic camera.] "Greenlighting" is when a studio executive gives the go-ahead to start making the next great movie/TV show of our time. Recent examples include MacGruber and The Untitled Tony Danza Teaching High School Show. If only these execs remembered that Green means Stop.
LOGLINE: Reading has never been a strength of the Hollywood Executive. This is why agencies hire people whose actual title is "Reader." [Note to Non-Hollywood residents: The previous sentence is NOT a joke.] And if the Hollywood Exec does read, like your average 5-year old, it's only a few words at a time. The logline is a one sentence description of a script like, "Trucks turn into robots and climb the Great Pyramids of Giza." Captivating, right? Not as much as, "Trucks turn into robots and climb the Great Pyramids of Giza while Megan Fox runs in slow motion." Movie sold!!
ONE PAGER: A longer version of a logline -- often one page. For use with an executive who doesn't have ADD and/or a massive cocaine problem rendering an ability to focus comparable of that to a fruit fly. Such documents include things like plot, characters and other things that will be edited out in Post Production.
ONE SHEET: Not to be confused with a one pager (although it's easy to see how you could). A one sheet is a fancy word for a promotional poster for a movie/TV show. One sheets are often found in public transit stops, assistants' cubicles and other places the haut monde don't frequent.
