- The Running Man (2025), as Victoria Parrakis, per Wikipedia (encyclopedia entry)
Is Sandra Dickinson credited in The Running Man?
Yes. Wikipedia lists her as Victoria Parrakis in the 2025 film, making it her most recent film credit in the research set. IMDb, Rotten Tomatoes and Wikipedia disagree on some other titles, so a full credit list needs cross-checking before anyone treats one page as complete.
The implication: the headline credits are well documented, but the depth of her filmography depends on which database a reader trusts.
Who is Sandra Dickinson married to now?
IMDb’s biography records her marriage to Mark Osmond from 16 August 2009, and lists her earlier husbands as Peter Davison and Hugh Dickinson, per IMDb (film and TV database). No Tier 1 record in the research set confirms that current status.
Is Peter Davison still married to Sandra Dickinson?
- No. Wikidata records the marriage as running from 1978 and ending in divorce in 1994, per Wikidata (open structured database).
- According to Georges Journal (personal blog), the pair also appeared together in a 1983 Cinderella pantomime.
The catch: the Davison marriage is the best-documented relationship in the research set, yet the 1983 pantomime detail rests on a blog and should not be read as settled fact.
Who was Peter Davison’s first wife?
The research set does not establish whether Dickinson was Davison’s first wife. The inputs contain nothing on his other marriages, so this question stays open rather than being answered by inference.
The implication: the first-wife question needs a source on Davison’s earlier marriages before it can be answered either way.
How old is Sandra Dickinson?
Dickinson was born on October 20, 1948. Wikidata and Rotten Tomatoes give that date, Fandango lists the same day, and OnThisDay places her under October 20 in its birthday index.
When was Sandra Dickinson born?
- , per Wikidata (open structured database)
- Same date listed on a ticketing site profile (Fandango (ticketing site profile))
- Birth name Sandra Searles, per IMDb (film and TV database)
What this means: age is calculated from October 20, 1948 as of the day you read this. The research set carries no publication-date figure, so this article states no age.
What is Sandra Dickinson doing now?
The most recent film credit in the research set is The Running Man (2025). No confirmed current project appears in the inputs, so this section reports what is documented and stops there.
Which recent productions list Sandra Dickinson?
- The Running Man (2025), as Victoria Parrakis, per Wikipedia (encyclopedia entry)
- Jungle Beat 2: The Past (2025), voice of Zoog, according to Rotten Tomatoes (film review aggregator)
- Thunderbirds Are Go (2015–2020), as Grandma Tracy across 28 episodes, per IMDb (film and TV database)
A 2025 credit shows that work exists, not that a project is in production. The research set documents nothing beyond these listings, so any claim about upcoming work needs a fresh source.
The implication: the 2025 listings are the newest documented work, so any statement about current projects needs fresh reporting.
Where is Sandra Dickinson from?
Her birthplace is Washington, D.C., USA, per Wikipedia (encyclopedia entry). Wikipedia also says she grew up in Maryland with her younger brother, a claim the research marks as medium confidence and not checked against a primary record.
Where was Sandra Dickinson born?
- Washington, D.C., USA, per Wikidata (open structured database)
- Washington, District of Columbia, USA, per the IMDb biography (film and TV database)
The implication: birthplace and upbringing are separate facts. The birthplace is well sourced, while the Maryland upbringing is not yet confirmed.
Timeline signal
- : first credit as a waitress in The Final Programme, per Wikipedia (encyclopedia entry), which flags that claim as needing a citation
- : marriage to Peter Davison begins, per Wikidata (open structured database)
- : Trillian in the BBC television series, per Wikipedia (encyclopedia entry)
- : marriage to Peter Davison ends in divorce, per Wikidata (open structured database)
- : voice role in Balto, per Wikipedia (encyclopedia entry)
- : marriage to Mark Osmond, per IMDb (film and TV database)
- : Dory in The Batman, per Wikipedia (encyclopedia entry)
- : Victoria Parrakis in The Running Man, per Wikipedia (encyclopedia entry)
The catch: the 1973 debut conflicts with a low-reliability aggregator, which names a different 1973 title (FamousBirthdays (low-reliability aggregator)). Wikipedia is the stronger reference here, but the debut is not closed.
Confirmed vs. unconfirmed
Confirmed
- Born October 20, 1948 in Washington, D.C., per Wikidata (open structured database)
- Married Peter Davison in 1978, divorced in 1994, per Wikidata (open structured database)
- Trillian in the 1981 BBC series, per Wikipedia (encyclopedia entry)
- Victoria Parrakis in The Running Man (2025), per Wikipedia (encyclopedia entry)
Not yet confirmed

- The 1973 film debut, which Wikipedia itself flags for citation
- Growing up in Maryland, per Wikipedia (encyclopedia entry)

What the sources say
She has often played characters within the trope of a dumb blonde with a high-pitched voice.
Wikipedia (encyclopedia entry), unsigned article
She is best known for playing Trillian in the TV series adaptation of The Hitchhiker’s Guide to the Galaxy.
Doctor Who Guide, unsigned reference entry (Doctor Who Guide (reference database))
The implication: the two sources agree on the Trillian role, and they describe her type-casting in different terms. Readers should treat the first as an editorial characterization, not a fact about her career.
Where things stand
Dickinson’s birth date, birthplace and the Davison marriage are documented in Wikidata, the most structured source in the set. Her current marriage, her debut, and her upbringing are less settled, and her post-2025 work is not documented at all. Researchers who quote this record should confirm the birth date and spouse dates against Wikidata and IMDb, because anyone who skips that check risks repeating aggregator errors as fact.
