The Odd Couple (Gene Saks, 1968)

I think it's one of my favourite comedies. I think of Billy Wilder stuff that I love like The Apartment, but with The Odd Couple it's just the dialogue and the spark between Jack Lemmon and Walter Matthau. I think Matthau is possibly one of my favourite actors of all time, just for his natural comedy sense. He sets sparks in every single film he's in. I can't think of a film where he's not the best thing in it.

Slow West similarly has a two-central-character dynamic. What attracted you to the idea?

What attracted me was the idea of a shift where a mentor becomes a student and a student becomes a mentor. It's less of a real buddy movie relationship and more about a crossing of arcs.
