10 Most Disturbing Backstories Behind Quentin Tarantino Movie Side Characters

Christopher Walken's appearance in Pulp Fiction might have only lasted four minutes, but his monologue will forever be remembered. His brief performance as Captain Koons - a Vietnam veteran with a mission to traumatise - played an important role in the story of Bruce Willis' character, Butch.

While Butch is preparing to leave town, he realises he's forgotten something he can't do without: his father's war watch - a prized family heirloom. It's during a flashback that the audience discovers the reason why Butch holds the watch so dearly.

Captain Koons relays how he and Butch's father were prisoners of war during Vietnam. By all accounts it was a traumatic experience, not only did Butch's father die of dysentery but he also spent five years concealing the watch in his ass. Koons revealed he was also forced to stow the hunk of metal where the sun don't shine, for an additional two years.

Tarantino wrote the character, inspired by the hundreds of American vets who were held by the Vietcong. The longest to be imprisoned was Floyd James Thompson. He spent nine years in various camps, in which time he was beaten, starved and hung by his thumbs, spending up to five years in complete isolation.
