Doctor Strange: 31 Easter Eggs & References You Must See
21. The Links To The Other Doctor Strange
This is actually the fourth Doctor Strange movie, after the 1978 cult classic (it's awful), 1992's Dr Mordrid and the animated Doctor Strange from 2007. And there are a significant number of similarities between this film and the latter to warrant mention.
In both cases, Dr Strange is taught personally by the Ancient One about reality warping, and by Wong, and the Ancient One's disciples travel the world. Strange also has a female "sidekick", with Gina Atwater taking the place of Christine Palmer, and Baron Mordo is black and develops a resentment for what Strange and his fellow Sorcerors have become.
