It feels like it has been a week since any news that didn’t involve Disney has come out. The Mouse House recently held their D23 Expo and a flood of announcements were made, including some new information on the highly anticipated sequels Toy Story 3 and Cars 2.

Toy Story 3 basically just made a bunch of casting announcements. /Film picked up on some Tweets from director Lee Unkrich and Disney that revealed that John Morris, the boy who voiced Andy in Toy Story and Toy Story 2, has been cast once again in the role, which now sees Andy as an 18-year-old young man. Also added to the cast is a great collection of names, some of which are Pixar veterans. Lending their voices once again will be Bonnie Hunt (A Bug’s Life/Cars/Monsters Inc., Jerry Maguire) and Jeff Garlin (Wall-E, Curb Your Enthusiasm); while new to the Pixar dance is Whoopi Goldberg (Ghost) and Timothy Dalton (Hot Fuzz), who will apparently be playing someone named Mr. Pricklepants.

Every Summer, Pixar releases their latest and greatest movie, which always seems to be be even more loved than the last. Along with these movies, we usually get just a little teeny weeny look at what next Summer has in store for us in the form of a teaser trailer. This year was a special year though, because we knew that in 2010, Toy Story 3 would finally greet us…a decade after we last saw our favorite animated toys. Unfortunately, we quickly learned that Disney’s newest return to hand-drawn animation, The Princess and the Frog, would actually be the one teased in front of this year’s Up, and that Toy Story 3‘s teaser would show in front of the new 3-D double-feature re-release of Toy Story & Toy Story 2 this October. Thankfully, this did not last long!

In a joyous turn-of-events, Disney/Pixar chose not to make everyone wait that long, and hook the teaser to Up after all, and now, it is here to watch as many times as you want.

The trailer doesn’t show anything regarding the actual movie or where the story will be going; it’s basically just a delightful re-introduction to all of our favorite characters who are busy constructing the new title. It’s funny, cute, completely simple, and absolutely perfect until we get our hands on a full trailer.

Disney has shared some new information on the upcoming 3-D re-release of two of the most important movies in the evolution of computer animated movies — Toy Story and Toy Story 2. On October 2, 2009 for a limited time, you will have the opportunity to run out to theaters and see the cherished pair of movies together in double-feature fashion.

The re-release is for everyone to experience the two movies for the first time with their new 3-D makeover — a makeover that many older animated movies are getting, including Disney’s Beauty and the Beast.

Another reason this is being done, is to get folks more excited than they already are (which is tough to do) for the highly-anticipated June 18, 2010 3-D return of Buzz, Woody, and the rest of the gang in Toy Story 3. The first teaser trailer for Toy Story 3 is expected to be shown at the double feature event in October as well (instead of the usual Summer before tradition), in case you needed another reason to go. The third installment is directed by Lee Unkrich, who was a co-director on the first two films.
