Robert De Niro Joins Lionsgate Comedy About My Father (Photo Credit: Brigitte Lacombe) Acting legend Robert De Niro has signed on to star alongside comic and actor Sebastian Maniscalco in About My Father, a Lionsgate comedy loosely based on the life of Maniscalco. The two-time Oscar-winning actor will portray Salvo, the father of Sebastian, in the film. In the movie, when Sebastian tells his old-school Italian immigrant father that he is going to propose to his all-American girlfriend, Salvo insists on crashing a weekend with her tony parents. Though their cultures clash and it seems that the two families have nothing in common, by the end of the weekend they will be a family.
