Just an FYI, minors CAN enter into contracts. It is true infancy imparts a lack of capacity. However, minors can still enter contracts. They are voidable at the election of the minor party until a reasonable time after reaching the age of maturity unless the contract is for necessities, then it is not voidable.

The original version of A New Hope should enter the public domain in 2072.
The Special Edition of A New Hope should enter the public domain in 2092.
The despecialized edition uses work from the special edition and would not be legally distributable until at least 2092. But as to your question on resolution, I do not believe copyright law would differentiate between a work bases solely on the published resolution. As the other comment suggests, A high res scan of the original A New Hope, if it exists, would be in the public domain in 2072.
