This is a fun little film even if the plot twists and turns become a bit exhausting and ridiculous but the chemistry between Lemmon and Mills is absolutely electric and hilarious and under the direction of Billy Wilder they truly shine and it is nice to see Wilder be more naughty in his films even though his earlier films were far more sexier and funny then this one.
I was finding the humor forced at first and the movie certainly feels out of touch with the times but by the end I found it impossible not to be won over by the relationship that lies at the film's heart. A true reminder how enjoyable Jack Lemmon was as an actor!
In the 1970s Wilder made two incredible films that almost no one seems to know about. This is one of them. His late 60s comedies became so dyspeptically nasty that they had stopped being funny. With Avanti and Sherlock Holmes, Wilder rediscovered his lyrical side. The character of Miss Piggot is one of Wilder/Diamond's best creations and Juliet Mills is absolutely delightful. It is perhaps better than The Apartment.
Oddly enough I've always seemed to gravitate towards Wilder's lesser known films. Avanti! may be a little overlong but the strongest portions are among his best and maybe his best synthesis of trademark cynicism and his knack for love stories(well along with The Apartment). You could even say that it's one of the few films to acknowledge that cynicism is in arguably a form of sentimentality. A must see.
