Well that was an interesting movie.
It started out well, and I can see where it would be good for improvisers to see. But, then the last half hour seemed to undo all that.
For the first while, Peter Seller’s character refuses to drink, so you can see him trying to maintain his composure under trying circumstances. And it is funny. Then he gets some alcohol in him. He stops trying to maintain himself and he starts fitting in. Which isn’t funny.
Then of course the whole movie got ’60s on us. Let’s have a groovy party! Let’s have an elephant in it too. Let’s fill the house with foam.
My advice: Skip the last half hour. You can figure out how it ends.
