Company logos change between versions. For example, on the laserdisc, the movie starts with a 20-second silent Columbia logo (before the Castle Rock logo), and the end credits crawl includes (after the title of the movie has gone onscreen) a line-art logo "Released by Columbia Pictures/A Sony Pictures Entertainment company" that crawls up and stops, over the end of the music. On the international prints, the 1990-1997 Universal logo was played and it was also silent. The 1999 WB DVD skips the opening logo, starting with the Castle Rock logo instead, and where the Columbia logo at the end should appear as the music ends, a still clouds-and-shield WB logo appears instead (Distributed by WB/A Warner Communications Company). The Columbia versions are probably truer to the original theatrical release. See also The Shawshank Redemption.
