Tobacco imagery occurred in 1344 intervals across 239 films. There was a declining trend in the proportion of films (r=\u22120.515, p=0.022) and the proportion of intervals (r=\u22120.004, p&lt;0.001) with tobacco imagery over time. None of the films with tobacco imagery contained a warning for their audience against smoking. Chinese films contained more tobacco imagery than international films, and tobacco imagery related to minors and tobacco brands were present despite regulations.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Tobacco imagery remains in films in China.
