Toy Story will not stay as a trilogy - Tom Hanks has revealed a fourth installment 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 $1.6 billion at the worldwide box office.

The two previous movies were also crowd-pleasers - 1995's Toy Story took more than $300 million (£187 million), while its sequel in 1999 took $485 million (£303 million).

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

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