Passage: To avoid pressure, Jackson hired a different editor for each film. John Gilbert worked on the first film, Michael J. Horton and Jabez Olssen on the second and longtime Jackson collaborator Jamie Selkirk and Annie Collins on the third. Daily rushes would often last up to four hours, with scenes being done throughout 1999–2002 for the rough (4½ hours) assemblies of the films. In total, 1828 km (six million feet) of film was edited down to the 11 hours and 26 minutes (686 minutes) of extended running time. This was the final area of shaping of the films, when Jackson realised that sometimes the best scripting could be redundant on screen, as he picked apart scenes every day from multiple takes.

Question: What was the name of the person who had to go through and edit the multiple takes that were filmed?
