John Cusack and Adrien Brody are to star in 'Dragon Blade'.

The actors have signed on to star as Roman soldiers lost in ancient times alongside action star Jackie Chan in the upcoming historical epic, according to The Hollywood Reporter.

Speaking about the casting of Cusack and Brody, Chan said: ''I'm really excited to be in a movie with two of the most respected actors working today.''

Cusack will play Lucius, a Roman general who leads a legion of soldiers into the Han Dynasty in China while Brody will take on the role of Tiberius, who assassinates Rome's Consul Crassus and tries to hunt down Lucius.

Meanwhile, Chan will star as the Commander of the Protectorate of the Western Regions, who joins forces with Lucius in a bid to protect China's borders and sovereignty from Tiberius.

Brody said of joining 'Dragon Blade': ''It is a dream to finally work with Jackie. Aside from my longtime appreciation for his many talents, he is a beacon of generosity, and an inspiration to me.

''Dragon Blade is a tale of mythical proportions --- of good prevailing over evil - and an opportunity for me to explore a character whose ambition challenges his honour.''

Cusack added: ''I grew up watching Jackie Chan films and stood in awe of his talent, energy and spirit. This will be a great adventure for me.''

The movie - which is being directed by Daniel Lee and is inspired by a missing legion of Roman soldiers that travelled to China in 48 BCE - will soon begin shooting on location in the historic city of Dunhuang, western China and in the Gobi Desert.

'Dragon Blade' is scheduled for release on February 19 2015.
