An actor very much in the tradition of Italian comics, Montesano has demonstrated his talent in many sophisticated comedies, expecially when he has worked for important directors, like Monicelli or Steno. However, his qualities can also be seen in grotesque comedies or in films without any apparent meaning. He has been elected for PDS party in 1994 for the European Parliament. He is an avid fan of football, supporter of Lazio.
