Diamonds Are Forever (1971)

  This is the silliest adventure yet for Bond.  

Ok, so Sean Connery is back.  Apparently, he decided not to do another one after You Only Live Twice because he kept having fights on set with the producers.  Hence why they then hired Australian model George Lazenby for the next one.  But George didn't have a good time making the film either and refused to come back.  So they paid Connery a boatload of cash to come and make this one. 

Things got a little confused because I watched them out of order but this is supposed to be right after his wife died at the end of On Her Majesty's Secret Service.  Maybe because it happened to George Lazenby, Connery doesn't seem to give two fucks about canon.  Character development?  Psh!  What's that?

Anyway, Bond manages to kill Blofeld (this time he's Charles Gray) in the first third of the movie and then spends the rest of the time chasing after smuggled diamonds.  He picks up the trail in Amsterdam, hooking up with red-headed hottie smuggler Tiffany Case (Jill St. John).  Get it?  Tiffany as in little blue boxes full of sparklies.  Bond gets the diamond shipment over to L.A. in a coffin and gets driven to Vegas with them by a bunch of wise guys.  Because it's Vegas in the 70's.  Bond notices that everything seems connected to reclusive kingpin Willard Whyte, and begins snooping around.  He discovers that SURPRISE! Willard Whyte is Blofeld who is alive and has a perfect duplicate, even down to the signature white cat.  Blofeld is using the diamonds in a satellite array in order to focus a laser so powerful that it can blow up submarines.  Because that's how lasers work.  Bond and Tiffany work together to try and switch the master control tape to disable the satellite.

It's very silly, as I said before, but not horrible.  At least it's not trying to take itself so seriously. 

Also, Rob and I had the theory that since Blofeld has changed into at least four different people, he's just a smokescreen and the cat is actually the mastermind.  That's why it doesn't matter how many times Bond kills him, he always comes back.
