I thought the Criterion cut was the only Gilliam cut, though? It combines footage from both the American and European versions of the film. The original Gilliam cut, IIRC, was just a rough which was previewed to various institutions around the country while Gilliam was having a falling out with Universal.
Also, about Mr. Arkadin, that doesn't really count since none of the cuts truly make the film a complete piece. Its really just various institutions re-organizing random footage that Welles approved of, and even some that was meant to be left on the cutting room floor.
