The current lead gives the account dated anchors—1979, 2005, 2011, 2018—that can be checked directly. The linked authority record independently contributes the date 1979-05-11.

Editorial analysis

Why this record matters

The subject matters to the people & ideas register because the source frames it as american actress. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

The entry’s evidential value lies in the named roles, institutions and publications that can be tested against primary documentation. The source revision retrieved here is dated Aug 28, 2026. The linked authority identifier is Q1103579. VIAF identifies the subject as 168947981. The Library of Congress control number is no2011048629. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1979, 2005, 2011 and 2018.

Critical limits

Later biographies can compress uncertainty and repeat inherited reputations, so apparently settled claims may still require comparison. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Read biographical claims against dates, named institutions and the cited references. Distinguish a subject’s later reputation from evidence produced during their lifetime.
