As the writer of movies like Lethal Weapon, The Nice Guys, The Long Kiss Goodnight and Iron Man 3, Shane Black is a true screenwriting auteur, known for his scripts' pulse-racing action, quippy dialogue and genre-skewing surprises. At the heart of his stories are usually two odd-couple characters, who must overcome their differences to solve a problem or often a police case. And did we mention all of this is often happening against a Christmassy backdrop? 

Kiss Kiss Bang Bang – Shane’s 2005 festive film noir – ticked all the above boxes, and plenty more. As Christmas movies go, it's a cult classic renowned for its sharp satire and creative meta commentary on Tinseltown past and present. Robert Downey plays Harry – a petty thief who lands a Hollywood screen test after accidentally crashing an acting audition while running from cops after a botched toy story burglary. Adrift in LA over the holiday season, a string of strange events finds him reunited with his old childhood crush, Harmony (Michelle Monoghan) and entangled in a murder mystery with a gay private investigator named Perry (Val Kilmer).

Shane wrote the movie after a nine-year layover between projects. His previous film, spy thriller The Long Kiss Goodnight, has a huge cult following now but struggled at the box office on release, sparking a period of soul-searching for the screenwriter. In the conversation you’re about to hear, Shane explains how Kiss Kiss Bang Bang revitalised his love for movie-making. We discuss what is about Christmas that he can’t stop himself coming back to as a storyteller, to what degree this movie provided a comic template for Iron Man and the MCU, and how his first draft of Kiss Kiss Bang Bang was a romcom with intoxicating characters but no real plot. That is, until he planted a murder at the centre of it…
