Wilson will play Ricky the Dragon, who timid crayon Yellow (Ricci) encounters on her journey to put a stop to two drawing's attempts to take over Color City.

The cast have also pledged their support to the Crayon Collection initiative, which aims to repurpose crayons for schools and organisations that help less fortunate children.

Wilson, Ricci and others will be voicing a public service announcement benefitting the charity.

John D. Erakilis, one of the film's producers, commented: ''Our partnership with Crayoncollection.org is a dream come true. We have always hoped to educate and inspire young people with this film and now we have the opportunity benefit those in need.''

Wilson will next appear in 'Inherent Vice' and 'The Coup'.
