American film editor who shared the cutting of J.J. Abrams's Star Trek in 2009 and Star Trek Into Darkness in 2013 with Maryann Brandon.
Mary Jo Markey worked as an editor on J.J. Abrams's television series before following him into features, and co-edited Star Trek in 2009 with Maryann Brandon.
The pair split the reels between them rather than working on the same scenes, then shaped the whole film together with the director during post-production.
They reunited for Star Trek Into Darkness in 2013, which pits the Enterprise crew against Khan and Admiral Marcus and the warship Vengeance.
