I enjoyed this film and am surprised at the low rating (at time of writing).
It's really a Rom-Com of two people totally unsuited to each other, and the rest of the story people have already commented about.
Peter Sellers in this film, oozes smarminess, as the philanderer and gives a very strong performance. There are some excellent scenes here including a pure Inspector Clouseau moment, where Peter Sellers picks up the cases to take them out of the flat/house - hilarious, and worth the watch alone.
I liked the very late 1960's vibe to the picture, but the music/soundtrack missed the mark I thought (who was listening to this type of music in 1970?).
Poor Mike d'Abo sings well enough but he can't turn an average tune into Handbags and Gladrags sadly.
Goldie Hawn turns in a decent performance as the young blond air head. This also looks like this was her first major role in a film, and she does get to do her trademark giggle, which fortunately, was limited to just a couple of times. She did go on subsequently, to make many other films. Perhaps her most funniest moment on screen here, was in the lift.
The support cast were adequate, and the boyfriend (Nicky Henson) puts in a decent turn. An actor who I was impressed with, was Peter Sellers's friend Andrew, played by Tony Britton, who with a small part, played it so well.
Whilst here, another very good moment to look out for is when Sellers's character is on television giving his cooking instructions, which is full of double entendre's, not unlike the TV cooks I see nowadays.
Overall a good entertaining movie, and I'll certainly watch it again.
