THE PARTY: I wish the dog had eaten my invitation

THE PARTY (1968) is a single, not particularly funny joke stretched out over 99 increasingly excruciating minutes.
Peter Sellers plays a bumbling bit-part actor from India, Hrundi V.Bakshi, who is accidentally invited to an exclusive Hollywood party at the home of a producer whose film he has just wrecked.
The joke involves Bakshi inadvertently causing mounting mayhem as the evening wears on, but in order to keep the gag going for an hour and forty minutes director Blake Edwards serves it up sparingly and leaves Sellers to his own devices to fill in the downtime. It doesn't work.
The humour is spread way too thin and climaxes in an orgy of destruction which is only fun in a you-really-have-to-be-there kind of way.
THE PARTY was Sellers and Edwards only non-Pink Panther collaboration, and even the worst of those is better than this.
