Toy Story 4

Toy Story 4

Toy Story will not stay as a trilogy - Tom Hanks has revealed a fourth instalment is in the works.

The third outing of Woody, Buzz Lightyear and their toy room pals was a huge hit for bosses at Disney, becoming the highest-grossing film of 2010 with profits of more than $US1.6 billion ($A1.54 billion) at the worldwide box office.

The two previous movies were also crowd-pleasers - 1995's Toy Story took more than $US300 million ($A287.94 million), while its sequel in 1999 took $US485 million ($A465.5 million).

And Hanks, who voices cowboy Woody, has let slip to the BBC that producers are currently putting plans in place for a Toy Story 4.

"I think there will be, yeah. Yeah, yeah, think they're working on it now. There you go."
