There has to be at least a short list of films that have great-sounding titles but are close to unwatchable. Such is In Like Flint, the 1967 James Coburn espionage spoof and sequel to Our Man Flint (’66). I can think of only two others: Things To Do In Denver When You;re Dead and Midnight in the Garden of Evil.
All ’60s spy spoofs suck horribly — the Flint films, Dean Martin‘s Matt Helm films, Get Smart, The Man from U.N.C.L.E. and Casino Royale (’67), the James Bond take-off with David Niven, Peter Sellers, Woody Allen, etc.
In Like Flynt is a derivation of “In Like Flynn,”a 1940s slang term. The Wiki page says it means “having completed a goal or gained access as desired,” and that it’s “sometimes used to describe success in sexual seduction.”
Expanded: “The term is often believed to refer to movie star Errol Flynn. Flynn had a reputation for womanizing, consumption of alcohol and brawling. His freewheeling, hedonistic lifestyle caught up with him in November 1942 when two under-age girls, Betty Hansen and Peggy Satterlee, accused him of statutory rape. The trial took place in January and February 1943, and Flynn was cleared of the charges.
“According to etymologist Michael Quinion, the incident served to increase Flynn’s reputation as a hound, which led to the popular phrase ‘in like Flynn.’ Columnist Cecil Adams also examined the term’s origins and its relationship to Flynn. Many early sources attesting the phrase say it emerged as war slang during World War II.
