Uncertain or disputed:
The specific month of the Time revelation. Some sources suggest the profile was connected to an August 1974 issue; others simply say 1974. The film was released June 20, 1974, and the filming wrapped in early 1974 — the Time coverage would have appeared sometime around or after the release.
The name of the specific reporter who made the call. No reporter has been named in the secondary sources available for this research, and inventing a name without documentary evidence would violate the factual standards this article applies throughout.
The exact document or record that the Time researchers found that first triggered the discrepancy. Secondary sources describe the general process but do not specify whether it was a birth record, a census document, or something else.
The precise nature of the 1954 document mentioned in one source as a falsified record. If accurate, this would mean a formal document was created in the mid-1950s as part of the maintenance of the arrangement, potentially as Jack was approaching military service age. This detail appears in limited sources and has not been corroborated across the full range of sources examined.
Whether Jack’s birth is more precisely placed at June’s age 18 or 19. Some sources say 17, others say 18 or 19, reflecting the question of exactly when in 1937 he was born relative to June’s own 1918 birth date and the month of her birthday.
The identity of Jack’s biological father. Multiple candidates are named in the literature, with no genetic confirmation available. Nicholson has declined to pursue testing.
