By the late 1960s, movies began to tackle major social issues such as the Vietnam War, social injustice, drug use, and other themes. Photography became more prominent on posters that also tried to reflect the mood of movies, such as serious movies showing scenes of drug or alcohol use, and the age of the anti-hero in movies began to become more prominent, as movie posters began to show these characters and feature them more prominently. The era of the major blockbusters began in the late 1970s with <i>Star Wars</i>, which now went back to painted scenes. Movie posters in the 1980s increasingly used painted scenes that sometimes combined with photography. Famous artists such as Ansel Adams, Frank Frazetta and Bob Peak were all often involved in the production of movie posters.
