10 Conspiracy Movies That Will Make You Paranoid

10. Marathon Man

Marathon Man Dustin Hoffman
Paramount Pictures

Marathon Man, the 1976 John Schlesinger thriller about a history student caught up in a Nazi conspiracy, is one of the best in the genre.

Starring Dustin Hoffman, Roy Scheider, William Devane and Laurence Olivier in an Oscar-nominated performance, the film (based on the novel of the same name), exemplifies all there is to love about the seventies' love-affair with conspiracy thrillers, adopting a decidedly more violent tone to drive home its horror. Olivier, in particular, is absolutely bone-chilling as the story's Nazi war criminal, bringing his talents to bear in an excruciatingly painful torture sequence that would delay anyone's next visit to the dentist.

It was immediately controversial upon its release, but the real terror of Marathon Man lies in the way it's shot. It follows in the footsteps of Alan Pakula's 'Paranoid Trilogy', intimating an eerie atmosphere that refuses to subside up until the film's admittedly unfaithful ending, and while villains don't get any more clear-cut than, y'know, actual Nazis, the film derives its suspense from the deception of its leading characters; you, like Babe, never know who can be trusted.

Throw in a score composed by Michael Small, and you have one of the seventies best - and most iconic - conspiracy thrillers.

Content Producer/Presenter

WhatCulture's very own resident movie guy, Ewan has been working in the content creation biz for over 10 years now, having started as a freelance contributor to WhatCulture Gaming all the way back in 2015. After graduating with a First-Class Honours in History from Northumbria University in 2017 (where he won a prize for a totally killer dissertation on the Watergate years), Ewan took on the role of Comics Editor at WhatCulture and quickly developed WhatCulture Comics into one of the biggest superhero-focused channels on YouTube. He followed this with a brief hiatus at Screen Rant in 2021, where he worked across the Gaming and Film sections as a writer and editor, before returning to WhatCulture as a Senior Content Producer / Presenter in 2023. He started his own podcast, We Love Dad Movies, in 2022, and has contributed several written pieces to the Eisner-nominated comics website Shelfdust as well. In his current role, Ewan incorporates his love of cinema, comic books, and history into written pieces and video essays for WhatCulture's Film & TV channel, as well as WhatCulture Gaming and WhatCulture Horror, with a particular focus on nineties-era Dad Movies, old school Westerns, and Golden Age Hollywood Noir. John Carpenter is his fave, and he thinks Batman Beyond should never have been cancelled. If that's your vibe, you'll probably like his stuff.
