Phantom menace was a cut negative, but since most of the film went through some form of digital manipulation, its mostly 2K filmouts.
According to IMDB, TMP was processed through a 2k DI: http://www.imdb.com/title/tt0120915/technical?ref_=tt_ql_dt_7
Imdb is user-based. I’ve seen some blatant inaccuracies in the technical specs of certain movies listed there. TPM was indeed a cut neg in ‘99.
In 2011 they were able to reconstruct the movie directly from ILM’s digital filmout tapes, which were still readable after more than a decade. This got them as close to the true original negative as possible. I’m not sure what the procedure was for the remaining shots that never went through the computer at all, whether they were scanned in from the cut neg or whether they were sitting on the filmout tapes as well for some reason.
In any event, this final(?) version of the movie would have been assembled digitally as a 2k DI, but whoever edited the imdb page should’ve specified that this was not done until the 2011 release.
