==Later life==
After the war, Marks went on to write plays and films, including ''[[The Girl Who Couldn't Quite!]]'' (1947), ''[[Cloudburst (1951 film)|Cloudburst]]'' (1951), ''The Best Damn Lie'' (1957), ''[[Guns at Batasi]]'' (co-writer) (1964), ''[[Sebastian (1968 film)|Sebastian]]'' (1968), and ''[[Twisted Nerve]]'' (1968).<ref>{{cite web |url=https://www.imdb.com/name/nm0548896/ |title=Leo Marks |access-date=26 December 2014 |website=IMDb.com}}</ref>

Marks wrote the script for [[Michael Powell]]'s film ''[[Peeping Tom (1960 film)|Peeping Tom]]'' (1960), the story of a [[serial killer]] who films his victims while stabbing them. The film provoked critical revulsion at the time, and was described as "evil and pornographic."<ref name =telegraph/> The film was critically rehabilitated when younger directors, including [[Martin Scorsese]], expressed admiration for it and for Marks's script. Scorsese subsequently asked Marks to supply the voice of [[Satan]] in his 1988 film ''[[The Last Temptation of Christ (film)|The Last Temptation of Christ]].''

Marks and his wife Elena feature prominently in Hanff's 1973 book ''The Duchess of Bloomsbury Street'', her memoir of her trip to England in 1971 in the wake of the success of ''84, Charing Cross Road''.<ref>{{Cite book |last=Hanff |first=Helene |title=The Duchess of Bloomsbury Street |publisher=J.

In 1998, Marks published his account of his work in SOE – ''[[Between Silk and Cyanide|Between Silk and Cyanide: A Codemaker's Story 1941–1945]].'' The book was written in the early 1980s, but didn't receive UK Government approval for publication until 1998.<ref name =guardian/> Three of the poems published in the book were scrambled into the song "Dead Agents" by [[John Cale]] performed at the [[Institute of Contemporary Arts]], London, in April 1999.

Marks described himself as an [[agnostic]] in ''Between Silk and Cyanide,'' but frequently referred to his Jewish heritage.
