Limited release is a film distribution strategy of releasing a new film in a few theaters across a country, typically in major metropolitan markets.
The purpose is often used to gauge the appeal of specialty films, like documentaries, independent films and art films. A common practice by film studios is to give highly anticipated and critically acclaimed films a limited release on or before December 31 in Los Angeles County to qualify for an Academy Award nomination (as by its rules). The films are almost always released to a wider audience in January or February of the following year.
A platform release is a type of limited release in which a film opens in fewer theaters (typically 599 or fewer) than a wide release. If the film receives positive word of mouth, it is gradually expanded to more theaters, as the marketing campaign gains momentum. A successful film released in this manner has even the possibility of expanding into a wide release.
The advantage of the strategy is that marketing costs are conserved until a film's performance has been established, when the distributor may opt to increase advertising and push for a wider release. On the other hand, if it initially flops, the distributor can withdraw from the campaign, thus minimizing advertising and promotional expenditures.
In the early stages of a platform release, the key metric is the per-theater average gross, not the total box office gross. Art house and independent films that garner high per-theater averages are seen as likely candidates for a successful wider release. A distributor using this release strategy must take care not to expand too quickly in the early stages to prevent the (limited) audience from being spread too thin, which would reduce the per-theater average and so cause the film to appear weaker.
