Francis Ford Coppola used Blow-Up as an inspiration for his 1974 thriller The Conversation in which an expert sound surveillance man played by Gene Hackman gets mixed up in a murder mystery.

Brian De Palma's 1981 thriller Blow Out starring John Travolta and Nancy Allen paid unofficial homage to Blow-Up with its plot. Travolta played a Hollywood sound engineer who happens to record a Chappaquiddick-like car accident involving a politician and a prostitute and begins to obsessively put together pieces of the puzzle in order to find out what really happened.

Several other films including High Anxiety (1977) and Blade Runner (1982) have used the plot device of blowing up a photograph in order to see a hidden detail in an image that proves pivotal.

In the season 3 episode of the popular 1970s television show The Brady Bunch titled "Click" Greg obsessively blows up a photograph he took at the high school football game in order to reveal a game-changing detail that was previously missed.

There is a brief scene in Amy Heckerling's 2007 romantic comedy I Could Never Be Your Woman in which Paul Rudd and Michelle Pfeiffer playfully re-enact the famous scene in Blow-Up in which Thomas straddles Veruschka while taking her photograph.

In the original music video to Seal's 1995 hit song "A Kiss from a Rose" he plays a fashion photographer who at one point re-creates the sensual Veruschka/Thomas scene with a model.

The first two Austin Powers films pay subtle homage to Blow-Up in scenes that feature Austin (Mike Myers) taking photographs at fashion photo shoots.
