Film making duo Nanni Moretti and producer Angelo Barbagallo have separated after 20 years of film making together, Italian media reported Wednesday.

The pair's prolific collaboration has produced Moretti's best-known work such as Dear Diary (Caro Diario, 1993), April (Aprile, 1998), 2001 Palme d'Or winner The Son's Room (La Stanza del Figlio) and the anti-Silvio Berlusconi themed comedy-drama The Caiman (Il Caimano, 2006) as well as many other titles.

The couple is said to have formed Rome-based Sacher Films when Moretti phoned Barbagallo in 1986 and proposed producing films outside the sphere of influence of media magnate and (twice Italian Prime Minister) Silvio Berlusconi's backing.

Berlusconi has long been a player in Italian film business either through his holding company Fininvest that backs Medusa or through his influence (when Premier) over Italian parliament and, subsequently, RAI State TV funds.

Moretti's wry humor, his penchant for exposing the lone individual confronting intimate struggles and a noted flair for political and family-themed dramas have assured the teams appeal both locally and abroad.

Angelo Barbagallo confirmed the separation, saying, 'I confirm the separation between Nanni and me but it is consensual between old friends and without trauma.'

The two will be taking separate paths for the time being: Moretti will lead the Turin Festival, which is in its 25th edition. He will also star in the upcoming Domenico Procacci (Fandango) produced Calm Chaos (Caos Calmo) while Barbagallo will be producing Marco Tullio Giordana's Crazy Blood (Sangue Pazzo) for RAI.

Other past Moretti and Barbagallo producing credits include favorites such as The Second Time (La Seconda Volta, 1995) by Mimmo Calopresti, Daniele Luchetti's The Yes Man (Il Portaborse, 1991) and It's Happening Tomorrow (Domani Accadrà, 1988).
