This came up on ITV1 recently, so recorded it as I hadn't seen it since seeing it in the cinema way back in 1967, and have to say what on earth did I go to see it for then, for it hasn't travelled well at all, and is typical of it's time with a mish-mash of trendy effects, and a disjointed comedy script, but what do you expect from 10 script writers and 5 directors.
Despite being a big fan of Peter Sellers, I found Woody Allen the funniest (in the few scenes he was in), so what with him and oodles of gorgeous dolly birds, it was just about worth my time.
**EDIT Forgot to mention the theme tune, written by Burt Bacharach and played by Herb Alpert & The Tijuana Brass, which is quite jaunty and a catchy ear-worm.
