Industry and technical terms used across the guides on this site, in plain language. Several of them are directly useful when you are trying to place a film you can only half remember — aspect ratio, Academy ratio and pan and scan all help narrow an era, and the casting terms explain why an announcement you remember may never have led to an actual film.
- Academy ratio
- The 1.37:1 frame used as the industry standard from the early 1930s until widescreen arrived in the 1950s. A nearly-square image is one of the fastest ways to date a film you can only picture.
- Anamorphic
- A lens system that squeezes a wide image onto standard film, then unsqueezes it in projection. It produces the very wide frame and the horizontal lens flares associated with big-budget cinema.
- Aspect ratio
- The proportion of width to height in the frame. Common values are 1.37:1 (Academy), 1.85:1 (widescreen) and 2.39:1 (scope). Remembering the shape of a frame narrows a film to a rough era.
- Attached
- Trade language meaning a performer or director is publicly associated with a project but has not necessarily signed. Weaker than “signed”, stronger than “in talks”, and projects lose attached talent routinely.
- Box office gross
- Total ticket revenue before anyone is paid. It is not profit: cinemas keep roughly half domestically, and marketing is not counted at all.
- Break-even
- The point at which a film has recouped production and marketing costs out of the studio share of ticket sales. A common rule of thumb is roughly two to two-and-a-half times the production budget.
- Cold open
- A scene that runs before the titles, often unrelated to the main plot. Common in television and in long-running film franchises.
- Day-and-date
- Releasing a title in cinemas and on a streaming service or digital store on the same day, rather than staggering the two.
- Development hell
- The state of a project that has been announced, optioned or scripted but repeatedly fails to begin production. Some films sit in it for decades.
- Director's cut
- A version reflecting the director’s preferred edit rather than the one released theatrically. It can differ substantially in length, tone and ending, which is a frequent source of “I remember it differently”.
- Dolly zoom
- Moving the camera towards or away from a subject while zooming the opposite direction, so the subject stays the same size while the background warps. Highly memorable and often the detail people recall.
- Domestic gross
- Ticket revenue from the United States and Canada, reported separately from international takings.
- Exhibitor split
- The share of ticket revenue kept by cinemas rather than the distributor. Typically around half domestically, and higher in some international markets.
- First-look deal
- An arrangement giving a studio the first opportunity to finance or distribute a creator’s next project before it can be offered elsewhere.
- Four-quadrant film
- A film aimed at all four audience quadrants: male and female, under and over 25. Usually implies a broad, family-accessible tentpole.
- Greenlight
- Formal approval to proceed to production with committed financing. Announcements before a greenlight are intentions, not commitments.
- IMAX
- A large-format presentation system. True IMAX film uses a much larger negative and a taller frame; many modern “IMAX” screens are digital and closer to standard widescreen.
- In talks
- Trade language meaning negotiations have begun. The weakest of the common casting signals, and the one most likely to come to nothing.
- Legs
- A film’s ability to keep earning after its opening weekend. A film with legs drops slowly week to week; one without collapses.
- Letterboxing
- Preserving a wide image on a narrower screen by adding black bars above and below, rather than cropping the sides.
- Limited release
- Opening in a small number of cinemas, often to qualify for awards or to build reviews before a wider rollout.
- Limited series
- A series told in a single season by design. Distinct from a show cancelled after one season, though the two are easy to confuse in hindsight.
- MPA rating
- The Motion Picture Association classification (G, PG, PG-13, R, NC-17) used in the United States. It is assigned by a board, is advisory rather than legal, and differs from ratings used elsewhere.
- Opening weekend
- The first Friday-to-Sunday of wide release. It disproportionately determines screen counts, marketing spend and how a film is publicly judged.
- Output deal
- A standing agreement giving a service rights to a studio’s output for a defined window. Output deals are why a whole studio’s catalogue can move platforms at once.
- Pan and scan
- Cropping a widescreen film to fill a narrower screen, discarding the sides of the frame. It changes composition significantly and was standard on older television broadcasts.
- Practical effects
- Effects achieved in-camera with physical props, makeup, models or stunts rather than added digitally. Often combined with digital work in the same shot.
- Prestige TV
- Television made with film-level budgets, limited episode counts and named directors. The term describes an economic model as much as a quality level.
- Reshoots
- Additional photography after principal shooting ends. Routine on large productions and not by itself a sign of trouble, despite how it is usually reported.
- Rotoscoping
- Tracing over footage frame by frame, historically for animation and now mostly for isolating elements in visual effects work.
- Second unit
- A parallel crew shooting material that does not need the principal cast, such as action, stunts, landscapes and inserts.
- Showrunner
- The person with day-to-day creative and management authority over a television series. Usually the head writer and an executive producer.
- Streaming window
- The period during which a service holds rights to a title. When it closes, the title leaves, which is why films disappear without notice.
- Tentpole
- A large release a studio builds its financial year around, expected to support the rest of the slate.
- Theatrical window
- The exclusive period a film plays in cinemas before moving to digital or streaming. It has shortened considerably from the traditional 90 days.
- VOD and PVOD
- Video on demand, and premium video on demand. PVOD is the higher-priced early digital rental offered before standard VOD pricing.
