Actor Liam Neeson has teamed up with fellow Irishman Bono to write a movie script, but they have been working on the project for more than six years.

The Schindler's List star is close pals with the U2 frontman and they have been writing long-term together on a film about Irish showbands in the 1970s.

Neeson tells British magazine Radar, "He's a wonderful man. He's got an idea for a script which we've been working on for the past six years."

It is not the first time the two have worked on the same film - U2 provided a song for the soundtrack of 2002 movie Gangs of New York, which featured Neeson as a hoodlum.
