The toy line and new details about Toy Story 3 emerged Sunday at an off-site event as the Annual Toy Fair kicked off, according to The Hollywood Reporter.

Toy Story 3, set to open June 18, kicks off a multi-year deal between Pixar/Disney and Lego.

At the event, Disney/Pixar unveiled the first of nearly 250 Toy Story 3 toys, created in partnership with more than 20 toy companies, including Thinkway Toys, Mattel, the Lego Group, Hasbro, Jakks Pacific and Fisher-Price.

Toy Story 3 brings back the franchise's popular cast of toy characters along with more new characters than any Pixar film to date, which also means more toys.

"More original characters means more opportunity," Klaseus told THR. "Kids always look for something new, so this should keep the toy line interesting and add to Toy Story's longevity."

While a vast majority of Toy Story 3 merchandise buyers will be kids, there are also collectors and college kids who are attracted by the nostalgia factor after growing up with Toy Story, Klaseus told THR, citing some tracking results. The movie plot captures a similar sentiment as Andy, the owner of cowboy Woody and Buzz Lightyear goes off to college.

A deluxe Buzz Lightyear toy at the correct movie size that can say famous lines from the film is the biggest single Toy Story toy item over the franchise's history, according to Klaseus.

Toy Story 3 director Lee Unkrich and producer Darla K. Anderson on stage Sunday talked about how they spent the last four years crafting the summer sequel.

Unkrich later told THR that he still has more work to do on Toy Story 3. The film is currently being scored, and some animation and special effects work still has to be done.

He told THR that Pixar took the unprecedented step of sharing its animation computer data with toy makers to allow them to produce toys that are "pitch-perfect and like in the movie." He said Pixar is likely to use a similar approach for future movie-based toys as well.

In the latest movie, when Andy goes to college, his toys get donated to Sunnyside Daycare, which ends up being more "like a retirement home for toys," Unkrich told the crowd Sunday. A new trailer got a very positive reaction from press, kids and parents in the audience.

Tom Hanks, Tim Allen and other stars and fans had been asking for years when Toy Story 3 would happen, and so they were particularly delighted to finally bring it back to the silver screen, said the filmmakers.

The film's new characters highlighted Sunday are Ken and Barbie and purple teddy bear Lotso.
