How did Universal change Orson Welles’s original cut of Touch of Evil?

After Orson Welles delivered his rough cut of Touch of Evil to Universal, the studio made significant changes to the film while he was away shooting scenes for another project. Universal added new footage and edited the film down to a 93-minute runtime, effectively releasing it as a B movie against his wishes.12

Welles responded by writing an extensive memo detailing his preferred edits, but the studio ignored his instructions at the time. It was not until 1998, more than a decade after his death, that a 111-minute version of the film was released, which finally incorporated the changes outlined in his original notes.12
