  During production of Radioland Murders, Lucas confided to McCallum his plans for three new Star Wars movies. To further test the nascent digital technology just then becoming available, in part from developments they made on Young Indiana Jones, McCallum produced revised versions of A New Hope, The Empire Strikes Back, and Return of the Jedi – released in 1997 as the Special Editions.
  Assembling the teams that worked both in front of and behind the cameras, McCallum produced the next three films, which Lucas wrote and directed: Star Wars: Episode I – The Phantom Menace (1999), Star Wars: Episode II – Attack of the Clones (2002) and Star Wars: Episode III – Revenge of the Sith (2005). The Star Wars prequels also ushered in a new era of digital filmmaking, and McCallum played a leading role in its development, overseeing a team of creative and technical professionals that developed and created the industry's first all-digital production pipeline. McCallum makes a cameo appearance in The Phantom Menace near the end of the film when Palpatine arrives on Naboo.
