If you haven't seen any or all of the previous 20 Bond films, then you can catch yourself up by watching the trailers for all of the movies. Extremely enterprising YouTube user famouswillie (and other folks with an extraordinary amount of free time on their hands) have made us very happy Cinemites by doing the tedious uploading work for us.

After the jump check out the trailer for every Bond film up through Casino Royale, and some bonus video treats at the very bottom of the list.

These trailers also serve as a sort of visual history of film. It's especially eye-opening to contrast the Dr. No trailer with the one for Casino Royale. We certainly have come a long way, Mr. Bond.

1967's Casino Royale spoof with six different James Bonds, including Peter Sellers and David Niven, is pretty funny if you haven't seen it. The theme song became a hit for Herb Alpert and the Tijuana Brass. Here's the opening of it for your enjoyment.

Never Say Never Again was the second non EON Productions (the company that has produced all of the James Bond films that are considered to be "official") film to be produced. Through a series of legal battles, this film was produced outside of United Artists, but could only be made as a remake of Thunderball. Confused yet? They managed to lure Connery back to the role for this one, and the title comes from a quote he gave when he was asked if he would ever play James Bond again, after Diamonds Are Forever. His answer, "Never again." Even though it's not considered part of the main canon of films, it's worth finding and watching. Especially for Connery's famous urine sample scene.
