Chinese superstars Jackie Chan and Ziyi Zhang have signed up to sing the title track for upcoming Olympic-themed movie The One.
The acting duo will join fellow Chinese celebrities Lee-Hom Wang and Stefanie Sun to sing the movie's theme tune - entitled Stand Up - for the Wange Zhebin-produced venture.
The film depicts the life of Liu Changchun, China's first Olympian who represented the communist country at the Los Angeles games in 1932 after battling Japanese occupation to appear at the events.
It will act as a tribute to the 2008 Beijing Games, which have prompted calls for a boycott from international protesters who oppose the nation's oppressive hold over Tibet.
The One is set to be released in May (08), ahead of the Olympics in August.
