While it will be for Columbo that the late great actor Peter Falk will be best remembered, we should not overlook his Oscar-nominated performances in Murder inc. or Pocketful of Miracles; his subtlety in Wim Wenders’ Wings of Desire; or his brilliant work with John Cassavetes in Woman Under the Influence and Husbands.

Made in 1970, Husbands told the compelling story of 3 middle-aged men (Falk, Cassavetes, and Ben Gazzara), who re-examine their lives after the death of a close friend. After bar-hoping and long subway conversations, the trio decide to take a trip to London, in a hope of finding something long lost. It’s a love it or loathe it movie and depending on your point of view it’s brilliant, self-indulgent, funny, boring, frustrating, the best or the worst. When I first saw it, I was blown-away. Here was something more like a documentary, centered around 3 of the greatest improvised performances putt on film. I was breathless at their audacity and brilliance.

Cassavetes wrote the script after improvising scenes with Falk and Gazzara. Falk described his experience of working with Cassavetes as a director “shooting an actor when he might be unaware the camera was running.”

“You never knew when the camera might be going. And it was never: ‘Stop. Cut. Start again.’ John would walk in the middle of a scene and talk, and though you didn’t realize it, the camera kept going. So I never knew what the hell he was doing. But he ultimately made me, and I think every actor, less self-conscious, less aware of the camera than anybody I’ve ever worked with.”

It’s an amazing piece of cinema, an uncensored slice of life in all its humor, pain, emotion, charm and endless subterfuge.

During filming in 1970, the BBC followed Cassavetes and his actors in New York and London making a documentary for their Omnibus strand, examining the unique way this great director made his movies.
