Milo Ventimiglia says playing a beloved character is difficult. The actor portrays Jack Pearson on NBC's This is Us. “Jack is not a difficult man to embody but at times he’s hard to live up to. The audience, everyone has put this man on a pedestal, they’ve called him perfect. But who he is, he’s a fallible man." "He’s made his mistakes but I think, in his sincerity of wanting to correct them, on wanting to do better and just loving his family and loving his wife so simply, we aspire to be him.
